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.
