ZSI      ZM3140 HARD DISK DRIVE PRELIMINARY PRODUCT MANUAL  AUG. 1993

 Jumper Setting
 ==============

 The drive is shipped defaultly configured as a single drive,
 addressed as master.

 Jumper JP1 on the adapter board has the function described below.
 The information below defines jumper setting for configuring up to
 two drives on a signal AT bus.

 JP1 pins 1,3
     CLOSED  Single drive system
     CLOSED  Master drive in a dual-drives system
     OPEN    Slave drive in a dual-drive system


 Drives are selected by the DRV bit in the drive/head register and by
 a jumper, JP1, on the drive designating it as either a master or a
 slave. When the DRV bit is reset, the master drive is selected, and
 when the DRV bit is set, the slave drive is selected. When drives are
 daisy chained, one must be jumpered as the master and one as the
 slave. When a single drive is attached to the interface, it must be
 jumpered as the master.



 DC Power and pin connector assignments
 --------------------------------------
 The ZM3140 has a 4 pin DC power connector mounted on the PCB.

 The design features of ZM3140 which allow greater shock tolerance are
 the results of using rugged heads and media, a dedicated landing
 zone, closed loop srevo positioning and specially designed motor and
 actuator assemblies.

 Ten base mounting points are the standard provision. The drive is
 mounted using 6/32 screws; 1/8 max. insertion for the bottom. The
 system integrator should allow ventilation for the drive to ensure
 reliable drive operation over the operating temperature range.

 For additional vibration isolation, an external suspension system may
 be used.


 Drive Mechanism
 ---------------
 A brushless DC directly drive motor rotates the spindle at 3393 RPM.
 The motor/spindle assembly is balanced to provide minimal mechanical
 runout to the disks and to reduce the vibration of the HDA. A
 dynamic brake is used to provide a fast stop to the spindle motor
 when power is removed.


 Task File Interface Connector
 -----------------------------
 The ZM3140 has a 40 pin Task File interface connector (JP6) mounted
 on the printed circuit board. Two drives may be daisy chained
 together with this connector, and the maximum cable length is two
 feet.


 Air Filtrations System
 ----------------------
 Within the sealed enclosure, a 0.3 micron filter provides a clean
 environment to the heads and disks.


 Head Positioning Mechanism
 --------------------------
 The four read/write heads are supported by a mechanism coupled to the
 voice coil actuator.

 Introduction
 ------------
 The ZM-3140 series is a high performance 1 inch-height 126MB format-
 ted drive with 14ms average seek time, designed to operate on an IBM
 PC/AT or equivalent. Since the drive contains the Task File within
 its control logic, it requires a IDE adapter board to operate.

 Key Features
 ------------
 - High performance rotary voice coil actuator with embedded servo
   system

 - 2,7 RLL code

 - Internal air filtration system

 - Automatic actuator latch against inner stop upon power down

 - Microprocessor-controlled diagnostic routines that are
   automatically executed at start-up

 - Automatic error correction and retries

 - Block size 512 bytes

 - IBM Task File emulation

 - Up to two drives may be daisy-chained on this interface

 - Translate mode is provided to support any HDD type for BIOS

 Diagnostic Routines
 -------------------
 The microprocessor performs diagnostics upon application of power. If
 an error is detected, the drive will not come ready.
