P8, SPETEMBER 12, 1988 Notes on Installation ===================== Mounting Orientation -------------------- The MiniScribe 9000 Series uses industry-standard mounting for 5-1/4" Winchester Disk Drives. The 9000 Series are designed to be used in applications where the unit may experience shock and vibration at greater levels than larger and heavier disk drives. The drive may be mounted in any attitude. The 9000 drive is mounted using 6-32 UNC screws 1/4" maximum penetration. The customer must allow adequate ventilation to the drive to insure reliable operation. In as much as the drive frame acts as a heat sink to dissipate heat from the unit, the enclosure and mounting structure should be designed to allow natural convection of heat around the HDA and outer frame. If the enclosure is small or if natural convection is restricted, a fan may be required. Daisy Chaining the MiniScribe 9000 Drives ----------------------------------------- Up to seven 9000 Series drives may be connected to a single host controller/formatter. Control signals at J1 are transmitted via standard, daisy-chain interconnection. Data signals at J2 are trans- mitted via radially connected data-transfer lines. Note: Interface terminators RP4 and RP17 are installed only in the last physical drive in the control chain. Maximum number of drives = 7. J4 SCSI Connector ------------------ J4 is a 50-pin straight solder pin connector on the printed circuit board. This cable connector is used to send and receive information from the SCSI Host Adapter with keyed slots between pins 3 and 5, 23, 25 and 27, and 47 and 49. Recommended Mating Connector: Burndy FRS50BF-8P or equivalent. Recommended cable is a Belden 50 pin flat cable, part number 9LS8050 or equivalent. J3 DC Power Connector ---------------------- J3 is a 4 pin keyed connector on the printed circuit board. DC power (+5V and +12V) is supplied to the drive via this connector. Recommend connector: AMP 350543-1 Pins: AMP 350078-4 Note 1: Equivalent of the above are permissible. Note 2. Suggested wire size 18 AWG. Electrical Interface -------------------- SCSI uses single-ended drivers and receivers which allow a maximum cable length of 20 feet (6 meters) from the first to the last device (up to 8 devices) on the bus. All assigned signals are terminated with 220 ohms to +5 volts and 330 ohms to ground at each end of the cable. Both two (2) terminator networks on the 9380S are removable. All signals driven by the drive are open collector and have the output characteristics as follows. Signal Assertion 0.0 VDC to 0.8 VDC Max. Driver Output 48mA (sinking) at @ 0.5 VDC Signal Negation 2.5 to 5.25 VDC All signals received by the drive shall have the following input characteristics. Signal True 0.0 V DC to 0.8 V DC Maximum Total Input Load -0.4 mA @ 0.4 V DC Signal False 2.5 to 5.25 V DC Minimum Input Hyteresis 0.2 V DC ********************************************************************** F E A T U R E S ********************************************************************** MINISC. 9380S PRODUCT MANUAL P/N 1093 REV. P8, SEPTEMBER 12, 1988 Introduction ------------ The MiniScribe 9000 Series of disk drives are low cost, high capacity, high performance random access storage devices utilizing 5 1/4" this film disks as storage media. Each disk surface employs one moveable head to access the data tracks. The 9000 Series features capacities of 380 megabytes (unformatted storage capacity). The 9000 disk drives utilize advanced 3380 Whitney-type head flexures and sliders which allow closer spacing of disks, allowing a higher number of disks in a standard 5 1/4" package.

A multiple defect is defined as 2 bytes or longer, or as a track with more than 1 single defect. Caution/Warning --------------- The Miniscribe drive is a precision product. During handling the unit must not be dropped, jarred or bumped. Otherwise, damage to the heads and disks may occur. When the drive is removed from the Miniscribe shipping container and not immediately secured within a chassis through its shock mounts, it must be stored on a padded, grounded, antistatic surface. Failure to comply with the above procedure will render null and void all warranties.
