When J9 is shorted with a jumper, the drive will be offline to the system and enter a seek exercise routione. OPEN Normal Operation CLOSED Seek Exercise The microprocessor performs a series of "wake up" diagnostics upon application of power. If an error is detected, the microprocessor will flash an error code by blinking the activity LED. Some errors may not allow the drive to return to the program until power is cycled. If no errors are detected, the microprocessor checks the configura- tion of the diagnostic Jumper J9. If installed, the drive enters a seek exercise routine. If removed (normal operation) the drive will remain in an idle state waiting for control signals. If an error is detected during the exercise routine an error code will be flashed by blinking the activity LED. Note: The drive select jumper can be used to initiate the J9 exer- cise. ********************************************************************** I N S T A L L ********************************************************************** MINISC. 6032/6053/6079/6085/6128 PRODUCT MANUAL P/N 1011 REV.

Mechanically isolated mounting points ------------------------------------- Four side mounting and four base mounting points are provided to the customer. Each mounting point is mechanically isolated from the drive. Additionally, four side mounting points are provided which are compatible with a full height floppy disk drive. Mounting Configuration ---------------------- The Miniscribe 6000 series of full height drives 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 is mounted using 6-32 screws, 1/4 inch maximum penetration. The customer should allow adequate ventilation to prevent the drive from exceeding the specified operating environmental temperature. Excessive operating temperature will reduce MTBF and specified data reliability. Cabling ------- Attach interface cables in the following order: P4, P1, P2, P3, with Connectors to J4, J1, J2 and J3 respectively. If multiple drives are to be interconnected, remove the terminator packs in all but the last drive of the daisy chain.

The recommended mating connector is AMP P/N 62187-1. If used, the hole in P4 will accommodate a wire size of 18 AWG max. Electrical Interface -------------------- The interface to any MiniScribe 6000 can be divided into three sections, each of which is physically separated: Control Signals, Data Signals and DC Power. All control Signals are digital in nature (open collector TTL), and either provide signals to the drive (input) or signals to the collector (output). The Data Signals are differential in nature and provide data either to (write) or from (read) the drive. The interconnecting cables between the drive and controller may be flat ribbon or twisted pairs of a length not to exceed 20 feet. The signal return lines and ground lines for P1 and P2 should be grounded at the controller. The voltage return lines of P3 should only be grounded at the power supply. Connector P4 is a spade lug connector tied to frame ground. ********************************************************************** F E A T U R E S ********************************************************************** MINISC. 6032/6053/6079/6085/6128 PRODUCT MANUAL P/N 1011 REV. G Introduction ------------ The Miniscribe 6000 series of disk drives are full height random access storage devices of 32, 53, and 85 megabytes (MFM Mode), 79 and 128 megabytes (RLL mode) (unformatted capacities). The drives contain up to five oxide 5 1/4 inch disks and utilize Whitney Style flexure technology. With one disk surface dedicated to continuous servo data, each other surface employs a movable head to service the data tracks. High performance and high unit reliability are achieved by the utili- zation of microprocessor control, a linear voice coil, and a closed loop servo positioning system. The heads, disks, and actuator assemblies are within a sealed enclosure containing a recirculating and breather filter to supply clean air and equalized pressure to the head and disk environment. Quality mechanical construction with a sophisticated single printed circuit board allows for maintenance free operation throughout the life of the drive. The 6000 series uses the industry standard ST506/412 interface. The 6032, 6053, and 6085 MFM models have a 5 megabit per second transfer rate. The 6079 and 6128 RLL models utilize the 7.5 megabit per second data transfer rate. The drives also feature power up diagnostics, buffered seek, a brushless DC spin motor, dedicated shipping zone and automatic locking actuator. Seek time --------- (Including settling time) | 6000 | ----------------------------+-----------+ Single Track | 6 ms | Average | 28 ms | Maximum | 55 ms | Average Latency | 8.33 ms | ----------------------------+-----------+ Start time (max) 20 seconds from power on to -READY Stop time (max) 10 seconds from power removal Reliability and Maintenance --------------------------- MTBF 25,000 POH (At 25*C Operating Environment) MTTR 30 minutes Preventive Maintenance None required Component Design Life 5 years Media Defects ------------- Media defects are physical characteristics of the recording media resulting in repetitive read errors when a functional drive is operated within its specified operating conditions. A single defect is defined as beeing less than two bytes in length. A multiple defect is defined as up to three contiguous single defects. During the manufacture/test process, a certification test, consisting of a media verification, evaluates each drive and identifies the location of each media defect. These defects are labeled on the drives flaw map by head and cylinder address, and number of bytes from index. Media defects as shipped from MiniScribe: 6032 6053 6085 6079 6128 Maximum defects per drive: 32 53 85 79 128 Maximum defects per surface: 20 20 20 20 20 These defects may be a combination of single or multiple type defects. Cylinder zero shall be error free. Magnetic Field -------------- The externally induced magnetic flux density may not exceed 3 Gauss at the disk surface. Drive Mechanism --------------- A brushless DC direct drive motor rotates the spindle a 3600 rpm. The motor/spindle assembly is dynamically balanced to provide minimal mechanical runout to the disks. A dynamic brake is used to provide a fast stop to the spindle motor when power is removed. Air Filtration System --------------------- Within the sealed enclosure, a 0.3 micron filter along with a breather filter provides a clean, equalized pressure environment to the HDA for the life of the drive. Head Positioning System ----------------------- The Read/Write and servo data heads are mounted on a ball bearing supported linear carriage, positioned by a linear voice coil motor, and driven by a closed loop servo system. This design allows for an increase in the number of data tracks. Position reference is made to tracks recorded on the dedicated servo surface located on the bottom side of the bottom disk. Track Zero Detection -------------------- Track Zero detection utilizes data encoded at the factory on the servo disk, which is read by the servo head. The servo disk is the bottom surface of the disk closest to the printed circuit board (PCB). Automatic carriage retract and locking -------------------------------------- When power is removed from the drive, the carriage will automatically retract and be latched in a non data area located at the inner most portion of the disk. Driver/Receiver charateristics ------------------------------ Low state (true): 0.0 to 0.4 VDC, -40ma max. High state (false): 2.5 to 5.25 VDC, 250 a Write Precompensation --------------------- In recording, to optimize data integrity and meet the error rate specification, write data presented to the controller may need to be precompensated from cylinder 512 and up. The need for write pre- compensation may vary with controller manufacturers.
