The shipping lock effectively locks the actuator during shipment and releases on application of 12V. When installing the drive into an enclosure, the breather holes on the drive top cover must not be obstructed. The drive may be mounted in any orientation. It is supplied complete with antivibration mounts and threaded mounting brackets. The drive is mounted using 6/32 UNC screws with maximum penetration of 0.25 inch. The drive installation must provide adequate air flow to ensure that the maximum HDA temperature does not exceed 60*C.

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 (J1) lines and this pack must be removed from all except the last drive in the chain. J1/P1 Control Connector ------------------------ Control signals for the drive are provided via the 34 pin edge connector (P1/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 and is labelled. A key slot is provided between pins 4 and 6. The recommended mating connector is AMP ribbon connector A/N 88373-3. J2/P2 Data Connector --------------------- Radial connection of read/write data signals is provided via a 20 pin edge connector (P2/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. J7/P7 Power Connector ---------------------- DC power is provided via a 4 pin AMP Mate-N-Lok connector (P7/J7) P/N 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 r.m.s. 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 when the drive is installed. ********************************************************************** F E A T U R E S ********************************************************************** RODIME RO 3000 SERIES DISK DRIVE PRODUCT SPECIFICATION PRO-00077 Product Description =================== General ------- The RO 3000 series disk drives are random access storage devices which use four 95mm magnetic disks to provide up to 63.5 Megabytes of unformatted on line capacity. 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 4K of program memory is used for several drive operations and for all positioner control functions. These include velocity control for all seeks, fault detection and interface. Mechanical Assemblies --------------------- The drive uses the sealed enclosure principle of Winchester head/disk technology and provides a minimum contamination environment to maintain head/media integrity. An internal filter minimizes airborne contaminants within the drive housing. A breather filter on the drive housing cover reduces the ingress of contaminants through the bearings of the disk motor by minimising the pressure drop across them. Recording Heads and Disks ------------------------- The drive contains four disks with one read/write head per disk sur- face. One surface is dedicated to the servo information for the positioner. The electrical interface between the recording heads and the electronics board is by means of a flat flexible circuit cable which incorporates the pre-amplifier circuits for all of the recording heads. 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: e.g. Short, short, long, short = 2 (0010) +------------+--------------------------------------------------+ | Fault Code | Description | +------------+--------------------------------------------------+ | 01 (0001) | No sync. | +------------+--------------------------------------------------+ | 02 (0010) | No Track Zero | +------------+--------------------------------------------------+ | 03 (0011) | Motor speed outside +/- 1% tolerance after | | | power-up | +------------+--------------------------------------------------+ | 04 (0100) | Motor speed outside +10%, -5% tolerance in normal| | | operation | +------------+--------------------------------------------------+ | 05 (0101) | Seek error | +------------+--------------------------------------------------+ | 06 (0110) | STEP received while WRITE GATE is TRUE | +------------+--------------------------------------------------+ | 07 (0111) | WRITE FAULT | +------------+--------------------------------------------------+ | 08 (1000) | Microprocessor self-test fail (RAM) | +------------+--------------------------------------------------+ | 09 (1001) | Microprocessor self-test fail (ROM) | +------------+--------------------------------------------------+ | 10 (1010) | No INDEX | +------------+--------------------------------------------------+ | 11 (1011) | Motor not up to speed | +------------+--------------------------------------------------+ | 14 (1110) | Failed power up offset calibration | +------------+--------------------------------------------------+ | 15 (1111) | Failed power up access time calibration | +------------+--------------------------------------------------+ 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 and 1. This map will be supplied on a label fixed to the drive as well as an accompanying documentation. The maximum number of illigal addresses is as follows: RO 3055 : 35 RO 3045 : 30 RO 3065 : 40 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) Write Pre-Compensation ---------------------- During writing, it is required that an advance or delay be applied to MFM bits when they occur in certain patterns. This compensates for peak shift on the disk due to pulse crowding. The value of compensa- tion should be 10 to 12ns and be applied on cylinders 650 to 871.
