 Drive Address 0 is used as a "deselect" (i.e., no drive is selected).

 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:
           +      +

 Dimensions and Mounting
 -----------------------
 Recommended orientation is vertical on either side, or horizontal
 with the Device Electronics board down; other mounting orientations
 may be used provided the ambient air temperature around the drive is
 kept at or below 50*C (122*F).

 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.

 Interface Terminator RN11 is installed ONLY in the last physical
 drive in the control chain.

 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.

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.
