DISK DRIVE OPERATION

This chapter describes the operation of

the Winner 3A WA31273A / WA32543A / WA33203A /

WA32163A / WA31083A, Winner 2A WA32162A

functional subsystems. It is intended as a

guide to the operation of the drive, rather than a detailed theory of operation.

Drive Mechanism

This section describes the mechanism of the drive.

the Winner 3A WA31273A / WA32543A /

WA33203A / WA32163A / WA31083A, Winner 2A WA32162A

hard disk drive consists of a

mechanical sub-assembly and a printed circuit board assembly (PCBA) as shown in figure 5-
1.

5-1-1 Head Disk Assembly

The head/disk assembly (HDA) contains the mechanical sub-assemblies of the drive, which
are sealed between the aluminum-alloy base and cover. The HDA consists of the disk stack
assembly, rotary positioner assembly, head stack assembly, actuator latch assembly, and

base casting which includes the DC motor assembly. HDA assembly is done in a Class 100
clean room. These subassemblies cannot be adjusted or field repaired.

CAUTION: To avoid contamination in the HDA, never remove or adjust its cover and seals
Disassembling the HDA voids your warranty.

products are part of a one, two and three disk product family. The

Winner 3A

WA31273A / WA31083A

contains one magnetic disk and two read/write heads and uses

both sides of the magnetic disk. The

Winner 3A WA32543A / WA32163A, Winner 2A

WA32162A

have two magnetic disks and four read/write heads, and the

Winner 3A

WA33203A

has three magnetic disks and five read/write heads.

5-1-2 Base Casting Assembly

A one piece, aluminum-alloy base casting provides a mounting surface for the drive
mechanisms and PCBA. The base casting also plays the role as the flange for the DC spindle
motor assembly. A gasket provides a seal between the base and cover castings that enclose
the drive mechanism.
