 Drive Mounting and Installation
 -------------------------------
 The RO 5000R Series disk drives may be mounted in a host system in
 any orientation. The shipping lock effectively locks the actuator
 during shipment and releases on power on.

 A clearance of at least 0.1 inch must be provided between all drive

 Up to four RO 5000R series disk drives may be connected to any host
 system. When connecting more than one drive to the host, the control
 lines may be "daisy-chained" but the data lines require to be
 radially (individually) connected. Each drive is provided with a
 removeable resistor pack for the control interface lines (near J1)
 and this pack must be removed from all except the last drive in the
 chain.


 J1  Control Connector
 ---------------------
 Control signals for the drive are provided via the 34 pin edge
 connector J1. The pins are numbered 1 through 34 with the even
 pins located on the component side of the board. Pin 2 is located on
 the end of the board connector farthest from DC power connector. A
 key slot is provided between pins 4 and 6. The recommended mating
 connector is AMP ribbon connector A/N 88373-3.


 J2  Data Connector
 ------------------
 Radial connection of read/write data signals is provided via a 20 pin
 edge connector J2. The pins are numbered 1 through 20 with the
 even pins located on the component side of the board. The recommended
 mating connector is AMP ribbon connector A/N 88373-6.


 J3  Power Connector
 -------------------
 DC power is provided via a 4 pin AMP Mate-N-Lock connector part
 number 350211-1, or equivalent, mounted via the solder side of the
 board. The recommended mating connector is AMP P/N 1-480424-0
 utilising  AMP pins P/N 350078-4.


 Cabling
 -------
 It is recommended that the control and data interface signals should
 be carried by flat ribbon or twisted pair cable of maximum length 20
 feet. The power cables should likewise be twisted pairs of each line
 voltage and return.


 Radio Frequency Interference
 ----------------------------
 Electric field shall not exceed 2 volts/meter RMS in the range
 1.5Hz to 10GHz.


 Magnetic Field
 --------------
 There shall be no source of constant magnetic field which yields more
 than 0.0005 tesla measured in the location occupied by the magnetic
 heads.

RODIME   RO 5000R SERIES HARD DISK DRIVE  PRODUCT SPEC. PRO-22058-1


 Product Description
 ===================

 General
 -------
 The RO 5000R series disk drives are random access storage devices
 that use up to four 130mm diameter magnetic disks to provide up to
 133.875 megabytes of unformatted on line capacity. (One megabyte
 equals 1,000,000 bytes)

 A servo surface is used in conjunction with a rotary voice-coil
 positioner to achieve an average access time of 28 msec.

 A microprocessor with 8K of program memory is used to control drive
 operations. These operations include velocity control for all seeks,
 fault detection, and interface.


 Mechanical Assemblies
 ---------------------
 The drive uses the sealed enclosure principle of Winchester head/disk
 technology that provides a minimum contamination environment to
 maintain head/media integrity.

 An internal filter minimizes airborne contaminants within the drive
 housing. A breather filter located at a minimum pressure area of the
 enclosure ensures that internal pressures at critical sealing areas
 are maintained above ambient.


 Recording Heads and Disks
 -------------------------
 The drive contains up to four thin-film sputtered disks with one
 read/write head per disk surface. With the exception of the servo
 disk, data is recorded on both sides of each disk - one surface of
 the servo disk is dedicated to servo information for the positioner.
 Data is recorded to the disk using 2,7 RLL (run-length limited)
 coding.

 The electrical interface between the recording heads and the
 electronics board is by means of a flat flexible circuit cable which
 incorporates the preamplifier circuits for all of the recording
 heads.


 LED Indicator and Fault Codes
 -----------------------------
 A red LED indicator is provided on the facia and indicates that the
 drive is selected and ready. This LED is also used to flash error
 codes should certain fault conditions arise in the drive.

 The selected-and-ready LED is used to flash error messages should
 certain fault conditions arise on the drive. A four bit binary code
 is used (long flash = logical 1, short flash = logical 0) with the
 most significant bit occuring first. For example, short-short-long-
 short = 0010 = fault code 2.

 Illegal Addresses
 -----------------
 Each drive will be accompanied by a map indicating the number of
 bytes from INDEX which should not be used by the host. These will be
 identified by cylinder, head and byte number. No illigal addresses
 will exist in cylinders 0. The maximum number of illigal addresses
 allowed per drive model is as follows:

        RO 5130R: 40
        RO 5095R: 30
        RO 5057R: 18



 Data Access Time
 ----------------
 The data access time is defined as the cylinder access time plus
 rotational latency of the required address.

 Average latency:                      8.3 ms
 Average data access time ramp mode:  36.3 ms
 Head switching time:                  5us (maximum)


 Drive Life
 ----------
 The minimum drive service life is 36,000 power on hours. The drive is
 capable of 10,000 start/stop operations during service life.


 Data Interface
 --------------
 The RO 5000R series disk drives transmit and receive differential
 data coded in 2,7 RLL code. Decoding is performed by the host.
