drive.
In the event of a difference between the manufacturer's specifications and those outlined
in this document the latter shall take precedence.
2.2 APPUCABLE DOCUMENTS
The following is a list of the documents by which this specification is based. For more detail, please
reference these documents as required.

3.0 REQUIRED DESIGN FEATURES
The device must contain and maintain certain design features that are required in the workstation
environment. The following is a list of the appropriate design requirements:
3.1 MECHANICAUHARDWARE
1) The device must automatically move the recording heads to a landing zone (completely
free of user data) and latch them there, upon the loss of DC power, without operator or
software intervention.
2) Not require any periodic or preventive maintenance.
3) Mechanism is to have a breather and filtration system in the HDA.
4) Provide dynamic braking of the disks on a power-down cycle.
5) Require no sequencing of power.
6) Device must have a minimum of a 32K dual port buffer system.
7) Be capable of supporting a minimum 48 bit ECC.
8) Glitchless drivers/receivers are to be used on the SCSI bus.
9) A set of adjacent pins, on the front of the drive, so that a cable for a remote LED
indicator can be used.
