The following characteristics apply to the DRIVE SELECT lines: 1. Logical unit designation is accomplished at the time of installation by setting the jumper plug located on the printed Circuit board. 2. All command cable lines are gated with DRIVE SELECT. No data cable signal lines are gated with DRIVE SELECT. 3. DRIVE SELECT must remain asserted during any communication with the host controller. 4. When the radial select jumper is installed, the drive is selected all the time. 5. The drive should not be selected until 1 second after DC power is applied. The Drive READY input is valid within 500 ns after the drive is selected (DRIVE SELECT true) and after the power on delay. 6. The drive is selected within 1 us after the assertion of DRIVE SELECT, if the power on sequence is complete. The drive will be the deselected within 1 us after the negation of DRIVE SELECT. 7. The drive activates the data cable DRIVE SELECTED signal within 1 us after receipt of DRIVE SELECT if the drive is selected. The drive negates DRIVE SELECTED within 1 us after the DRIVE SELECT signal is negated. 8. DRIVE SELECT must be valid 100 ns minimum before the first step pulse is received and 100 ns minimum after the last step pulse is received. 9. At the completion of a write operation, DRIVE SELECT must remain asserted for 1 us. 10. When the DRIVE SELECT line is asserted, a head change occurs, thus requiring a delay of 5 us before a read or write operation can be initiated. J7 Radial Select ----------------- 9-10 OPEN Radial disable CLOSED Radial enable J7 External Spindle Clock (Option) ----------------------------------- 11-12 OPEN Spindle Sync disabled CLOSED Spindle Sync enabled The external spindle clock options allow for synchronized rotation of a few disk drives in a system. Each drive can be configured to one of the following modes: a. Use internal spindle clock, output spindle reference clock. b. Use internal spindle clock with a line terminator. c. Use external spindle clock without the line terminator. Motor On Command (Optional) --------------------------- When the Motor On Command option is installed, the Motor On input line controls the drive spin up and spin down operation. This line is terminated with 220 ohm to +5V and with 330 ohm to ground. The terminator is not removable. The Motor On signal is asserted when high. There is no need to select the drive for spin up/spin down operation. ********************************************************************** I N S T A L L ********************************************************************** SEAGATE ST1100/ST1150R PRODUCT MANUAL 36136-001, REV.

Drive Orientation ----------------- The permissible drive mounting orientations include operation in the horizontal plane with PCB down and in the vertical plane. Mounting with either end down (front or rear) is not permissible. The SWIFT is designed, manufactured, and tested with a "Plug-in and Play" installation philosophy. Basically, this philosophy minimizes the requirements for highly trained personnel to integrate the SWIFT into the OEM's system, wether in a factory or field environment. Front Panel ----------- The SWIFT is available with a black front panel. The panel has a single green rectangular lens through which ligth from a LED mounted on the PWA radiates. The LED indicates the drive is selected when glowing. A flashing LED indicates the presence of a nonrecoverable fault. A fault indication is displayed irrespective of DRIVE SELECT status. Cooling ------- The Cabinet cooling must be designed by the customer so that the ambient temperature immediately surrounding the SWIFT does not exceed temperature conditions. Sway ---- The sway of the HDA left to right and front to rear is within the envelope. The sway of the HDA up and down is 0.05 inch outside the envelope.

Daisychain Configuration ------------------------ A daisychain configuration incorporates parallel interfacing of the disk drives on a common command cable. A maximum of four drives may be daisychained on the command cable. Only the drive which is selected by the host system has its control and data signals enabled through this common interface. View B consists of four SWIFT disk drives only. A terminator resistor pack is required in the host controller for each data cable. Only the last SWIFT in the daisychain requires a terminator resistor pack for the command cable. Terminator resistor packs for the command cable or other drives are removed. The total combined command cable length (from the controller to the first drive, to the second and subsequent drives) must not be more than 20 feet (6.1 meters). DC Cable and Connector ---------------------- The SWIFT receives DC power through a 4 pin connector mounted on the HDA. Recommended part numbers for the mating connector are included below, but equivalent parts may be used. Type of cable: 18 AWG Connector: AMP 1-480424-0 Contacts: AMP 60619-4 (Loose Piece); AMP 61117-4 (Strip) Ground Connection ----------------- A quick disconnect, Amerlock MTL-1802-A, is provided on the drive chassis.

The recommended connector consists of: a. Du Pont Housing 69305-002 b. Du Pont Terminal 77138-001 or equivalent. The cable consists of two 28 AWG wires. The maximum cable length is 20 feet (6.1 meters). The external spindle clock connector header is mounted on the disk drive main PCB. J7 pins 11 and 12 are used for the external spindle clock connection. Interface Drivers/Receivers --------------------------- The SWIFT uses both single ended and balanced differential signals on the I/O. The data signals use balanced differential drivers and receivers. All other signals use single ended drivers and receivers. Single Ended Drivers/Receivers ------------------------------- Transmitter Characteristics The SWIFT uses a custom driver to transmit status to the host. This driver is capable of sinking a current of 24 mA with a low level output voltage of 0.4 V. Receiver Characteristics The SWIFT uses a custom receiver with hysteresis gate as a line receiver. The input of each receiver is terminated in a 220/330 ohm resistor network. Terminator Characteristics The terminator consists of a resistor module which plugs into a socket in the last drive in a daisychain. Each drive is furnished with a terminator. Terminators must be removed from all except the last drive on the cable prior to daisychain operation. The terminator can be easiliy removed with tweezers or needlenose pliers. Terminator installation, however, requires some disassembly of the drive. An equivalent terminator must be provided in the controller on each input signal line from the drive to the controller. Only the Command cable resistor module is removable. Balanced Differential Drivers/Receivers --------------------------------------- Transmitter Characteristics The SWIFT uses 75158 type balanced differential drivers. A signal on the interface is defined as asserted when the "+" output is more positive than the "-" output. Receiver Characteristics ------------------------ The SWIFT uses 75157 type balanced differential receivers. A signal on the interface is defined as asserted when the "+" input is more positive than the "-" input. Terminator Requirements ----------------------- Each differential receiver in the drive is terminated with a 100 ohm resistor. The terminator is a Beckman Industrial P/N L105C221/331F or equivalent. An equivalent terminator must be provided in the controller on each input signal line from the drive to the controller. Driver and Receiver ------------------- The external spindle clock signal utilized a balanced differential driver and receiver the same as those used for data transfer. The + signal is connected to J7 Pin 11 and the - signal is connected to J7 pin 12. The terminator used is the same as the one used for data transfer. ********************************************************************** F E A T U R E S ********************************************************************** SEAGATE ST1100/ST1150R PRODUCT MANUAL 36136-001, REV. B General Description ------------------- The SWIFT is a member of a family of low cost, high performance, highly reliable, random access storage devices designed to meet the needs of the OEM marketplace. The SWIFT interface consists of a 34 pin command interface cable and a 20 pin data interface cable which is compatible with the industry standard ST506/ST412 disk drive interfaces. The 34 pin command inter- face is designed to allow daisy chained or radial connections to additional SWIFT disk drives. Standards --------- The SWIFT has been developed as a system peripherals to the highest standards of design and construction. The SWIFT depends upon its host equipment to provide adequate power and environment in order to achieve optimum performance and compliance with applicable industry and governmental regualations. Special attention must be given in the areas of safety, power distribution, shielding, audible noise control, and temperature regulation. The SWIFT complies with CDC standards. The SWIFT is a UL Recognized component per UL478 and a CSA Certified product per CSA C22.2, No. 220-M1986. It also meets the requirements of DIN IEC 380/IEC 435/IEC 950/VDE 0806/8.81. The SWIFT, as delivered, is designed for system integration before use. It is supplied as a Class A Computing Device per the FCC Rules and Regulations, Part 15, Subpart J, governing EMI of computing devices. The SWIFT uses a dedicated landing zone at the innermost radius of the media where is no user data, thus eliminating the possibility of destroying or degrading customer data. Read/write heads are auto- matically moved to the landing zone upon loss of power. The SWIFT incorporates an automatic shipping look which prevents potential damage to the heads and discs caused by movements during shipping and handling. The shipping lock is automatically disengaged when power is applied to the drive and nominal spindle speed is achieved. The SWIFT decodes Track 0 location from the dedicated servo surface thereby eliminating mechanical transducer adjustments and related reliability concerns. The SWIFT uses a high performance actuator assembly consisting of a low inertia, patented straight arm driven by a highly efficient pancake coil assembly. This actuator mechanism provides excellent performance with minimal power dissipation. Media Description ----------------- The media used in the SWIFT has a diameter of approximately 95 mm. Each data surface has a total of 1072 tracks and is capable of recording 11,165,952 (16,748,928 RLL) bytes of unformatted data. Media defects are characterized as beeing either correctable or uncorrectable as a function of the type and magnitude of the media flaw. Various error correction codes may be implemented to correct errors in the data read from the disk. However, the code chosen should be consistent with Control Data media testing and certification methods. In the SWIFT media certification is performed using the following standards: An error burst of 11 bits or less is a correctable error. An uncorrectable error is one greater than 11 bits in length. Host systems using the SWIFT should have, as a minimum, resident capabilities to recognize and map defective tracks and perform track reallocation routines. At the time of shipment from the point of manufacture, the SWIFT recording surfaces meet the following requirements. 1. 1072 total tracks per surface. 2. Track 0 to be error free on each data surface. 3. 15 bad tracks per surface maximum (MFM Models). 20 bad tracks per surface maximum (RLL Models). 4. Accumulative defects not to exceed 1 per megabyte, based on total available unformatted drive capacity. Service Tools ------------- No special tools are required for site installation or recommended for site maintenance. Defect and Error Management --------------------------- The SWIFT, as delivered, complies with all aspects of this specification. The read error rate and specified storage capacity are not dependent upon the use of defect management routines. However, carefully chosen defect management methods can significantly enhance overall system performance. The application of error correction codes (ECC), and/or sector reallocation permits the continued use of the major portion, or perhaps all of a track when a defect is found. ECC is highly recommended since the majority of defects are correct- able. If ECC is not used, then all flagged defects will be essenti- ally uncorrectable and must be reallocated. Sector or track realloca- tion schemes are effective methods for relocating media defects. Sector reallocation in general is more efficient and may offer significant performance improvement. Acoustic Noise Level -------------------- Acoustic noise power level of the SWIFT should be less than TBD numbers bels during idle/operation mode. Equivalent typical average sound pressure level should be less than TBD numbers dba when measured with microphone at a distance of one meter from the drive. Custom Formatting ----------------- CDC maintains custom formatting capability which can accommodate many of the unique formats used in the Winchester marketplace. A majority of special format requirements can be implemented as specified by the customer. Unique format requirements should be identified as soon as possible to facilitate timely implementation. Drive/Receiver Characteristics ------------------------------ Interface signals levels and logical sense at the SWIFT I/O Connector are defined as follows: Logic Level Drive Output Receiver Input -------------------------------------------------------------------- High (false/negated) (0) 2.5 V; 5.25 V 2.0 V; 5.25 V Low (true/asserted) (1) 0.4 V; 0.0 V 0.5 V; 0.0 V The difference in the voltages between input and output signals is due to the losses in the cable. Seek Time --------- Models |16.5 MS |25 MS | ----------------------------------+--------+--------+ Track-to-track msec. max. | 4 | 5 | Average msec. typ. | 15 | 22 | Average msec. max. | 16.5 | 25 | Latency msec. avg. | 8.33 | 8.33 | ----------------------------------+--------+--------+ Seek time is defined as the time required from the receipt of a seek or position command by the SWIFT until the drive signals the controller that it is ready to perform another seek or a read/write function on the new cylinder. Average seek time is determined by dividing the sum of the time for all possible movements by the total number of movements. Spindle Speed and Latency ------------------------- The spindle speed is 3600 0.5% r/min. The speed tolerance includes motor performance and motor control circuit tolerances. The average latency time is 8.33 milliseconds, based on a nominal disc speed of 3600 r/min. The maximum latency time is 16.75 milli- seconds based on a minimum disc speed of 3582 r/min. Read Data Transfer Rate ----------------------- The nominal read serial data transfer rate is 5.0 Mbits per second, for MFM models and 7.5 Mbits per second for the RLL models. Power Sequencing ---------------- Power sequencing is not required for the SWIFT. The SWIFT protects against inadvertent writing during power up and down. Daisychain operation requires that power be maintained on the terminated unit to ensure proper termination of the peripheral I/O cables. Power sequencing can be obtained by using the motor on command option, if the drive has been configured for its use. Heat/Power Dissipation ---------------------- Each SWIFT will typically dissipate 10 watts (34 BTU per hour) of power during operation (seeking). Idle mode power dissipation is less than 8 watts, typically. Temperature ----------- 50*F to 122*F (10*C to 50*C) (dry air) operating ambient with a maximum gradient of 18* F (10* C) per hour. Above 1000 feet (305 meters) altitude the maximum temperature is derated linearly to 112*F (44* C) at 10,000 feet (3048 meters). Cabinet packaging designs must provide ample air circulation around the SWIFT to make sure environmental limits are not exceeded as a result of heat transfer from other system components. Operating ambient for specification purposes is defined as the environment immediately surrounding the SWIFT. The temperature of the HDA is restricted to a maximum of TBD during operation. System cooling consideration should avoid large thermal gradients between points A and B. Air Cleanliness --------------- The SWIFT is designed to operate in a typical office environment with minimum environmental control. Electromagnetic Emissions ------------------------- The SWIFT meets the performance requirements for electromagnetic emissions set forth in CDC-STD 1.03.208 which assures compliance with FCC rules and regulations. Chassis/DC ground separation ---------------------------- The SWIFT is provided with the chassis groung tied to DC logic ground. An option is provided for the user to isolate the chassis and logic grounds. This option may be beneficial in reducing ground induced noise in some system applications. Write Precompensation --------------------- RLL write data must conform to the conventional RLL encoding rules and must write precompensated by 12 ns per the industry standard RLL data write precompensation rules. Write precompensation is re- commended on all tracks; however, write precompensation must be performed on tracks greater than Track 300. No write precompensation is required for MFM. Options ------- All options are either incorporated or packaged at the manufacturing facility. Reliability ----------- The following reliability specifications require that correct host/drive operational interface has been implemented, including all interface timings, power supply voltages, environmental conditions, and appropriate data handling circuits in the host system. MTBF 30,000 hours Service Life 5 years Preventive Maintenance None required
