The three Drive Select interface lines are decoded to select the correspondingly addressed drive to the host controller/formatter. In multiple-drive systems, each drive must have its own unique address. Terminator Pack RN11 provides proper termination for the interface lines. When daisy-chaining multiple 1560 drives, the terminator is installed only in the last drive on the daisy chain. W1 Hard- or Soft-sectored mode ------------------------------- CLOSED The drive is configured to operate in the SOFT SECTOR mode. Address mark generation and detection are enabled, and the Sector/Address Mark Found interface signal is used to report address mark found. Sector size is selected by the host controller. OPEN The drive is configured to operate in the HARD SECTOR mode. The Sector/Address Mark Found interface signal is used to transmit sector pulses to the host controller. Sector pulses are derived from the servo disk. The number of sector pulses generated is equal to: + + |31,250| Where 31,250 = byte clock derived from servo INT|------| disk | n | INT = integer part of + + n = the number of unformatted bytes/ sector (82 minimum) W2/W3/W4 Hard Sector Configuration ----------------------------------- +--------+---------------------------+------------------------+ |Sectors | Bytes/Sector | Jumpers | | | Formatted Unformatted | W4 W3 W2 | +--------+---------------------------+------------------------+ | | Reserved | OPEN OPEN OPEN | | *54 | 512 577 | OPEN OPEN CLOSED| | 28 | 1024 1116 | OPEN CLOSED OPEN | | 14 | 2048 2232 | OPEN CLOSED CLOSED| | 7 | 4096 4464 | CLOSED OPEN OPEN | | | Reserved | CLOSED OPEN CLOSED| | 97 | 256 321 | CLOSED CLOSED OPEN | | 1 | 31248 31248 | CLOSED CLOSED CLOSED| +--------+---------------------------+------------------------+ * Factory default configuration W5 Spindle Control Option -------------------------- CLOSED The drive must wait for a Start Spindle command to start the spindle motor.

Inasmuch 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 natural convetion is limited, a fan may be required. The 1560 Series uses industry-standard mounting 5 -inch Winchester disk drives (the same as for 5 -inch flexible disk drives). Mounting Screws --------------- 2 per side 6-32 UNC-2B x 0.156 max deep. 4 on bottom 6-32 UNC-2B x 0.20 max deep Caution: The length of the mounting screws must be such that the screws do not penetrate the bottom mounting holes more than .20 inches and the side mounting holes more than .156 inches. Maximum torque applied to the screws must not exceed 10 in-lbs. Control Signal Connector J1 --------------------------- J1 is a 34-pin board-edge connector. The signals on this connector control the drive and transfer drive status to the host controller. Recommended Cable: 3M Scotchflex 3365/34 Mating Connector: AMP 88373-3 (key slot between pins 4 and 6) Data Transfer Connector J2 -------------------------- J2 is a 20-pin board-edge connector. The signals on this connector contain read or write data. Recommended Cable: 3M Scotchflex 3365/20 Mating Connector: AMP 88373-6 (key slot between pins 4 and 6) DC Power Connector J3 --------------------- J3 is a 4-pin, keyed AMP MATE-N-LOK Connector. This connector supplies DC power (+5V and +12V) to the drive. Mating Connector: AMP 1-480424-0 Pins: AMP 350078-4 Suggested Wire Size: 18 AWG Ground Connectors J4/J5 ----------------------- 3/16-inch spade lugs J4 and J5 are provided for grounding; system characteristics determine the proper ground connection. Mating Connector: AMP 60972-2 or equivalent.

Connectors J4 and J5 are provided for grounding; system characteristics determine the proper ground connection. Interface Electrical Characteristics ------------------------------------ The signals at Control Signal Connector J1 control the drive and transfer drive status to the host controller. The signals are low- true at the interface, high-true into drivers and out receivers, and have the following logic levels: True = 0.0 VDC to 0.4 VDC @ I = -48 milliamps (maximum) False = 2.5 VDC to 5.25 VDC @ I = +250 microamps (open collector) All interface data transfer signals are differential in nature. Up to seven drives can be connected to one host controller/formatter. Drive Select 1, 2 and 3 carry the binary-coded addres of the drive to be selected. The address of the drive is set with driveselection jumpers DA1, DA2, and DA3 as a binary combination. When the address is decoded and the decoded value matches the value specified by the three drive-selection jumpers, that drive is enabled to receive commands and transmit status. Drive Select 1 is the least significant bit. Adjustments and Maintenance --------------------------- The 1560 Series of drives requires no adjustments or periodic maintenance. Additionally, no mechanical adjustments are required to prepare the drives for handling or shipment. Field-Replaceable Components ---------------------------- The concept of repair by replacement of complete functional components is utilized in the 1560 Series, resulting in an MTTR of less than 15 minutes. ********************************************************************** F E A T U R E S ********************************************************************** MICROPL. 1560 SERIES PRODUCT DESCRIPTION 104742 REV. B Micropolis 1560 Series high-performance, 5 -inch Winchester Disk Drives provide OEMs with high-speed, high-capacity, random-access storage. They are fully compatible with the Serial mode of the Enhanced Small Device Interface (ESDI) standard and are designed to meet the needs of diverse applications environments. Media Defects ------------- Media defects are physical characteristics of the media which result in repetitive read errors when a functional drive is operated within specified operating conditions. At the time of manufacture, a media test system evaluates every drive and identifies each media defect location. The defects are logged on a label affixed to the drive. The defective areas are identified by head (HD) address, cylinder (CYL) address, and number of Bytes from Index (BFI). A printed listing of the defects is also shipped with each drive. A defect list is written for each data surface. The list is written on the corresponding surface in Sector 0 at three cylinder locations: 1) The maximum cylinder (1631). 2) The maximum cylinder minus 8 (1623). 3) A special cylinder which is accessed as "Cylinder 4095 (FFF in hex.)". This is in compliance with the industry-standard ESDI specfication. Do not attempt to write to Cylinder 4095. Micropolis specifies that all 1560-series disk drives will meet or surpass the following criteria: All drives shall have no more than one defect per megabyte of un- formatted media. Additionally, Cylinder 0 and the cylinder at 4095 shall be defect-free at the time of shipment. Head/Disk Assembly ------------------ The Head/Disk Assembly (HDA) consists of a die-cast structure that contains virtually all the drive's mechanical components. Two die- cast members create a sealed clean area. Components included in the clean area are the read/write heads, the magnetic disks, the head preamplifier, and the rotary positioner. Electrical connection between the mechanics in the clean area and the electronic circuit boards is made with flexible circuits. Data Transfer Signals --------------------- Four pairs of balanced signals are used to transfer data: NRZ Write Data, NRZ Read Data, Write Data Clock, and Read/Reference Clock.
