CHAPTER 5 DISK DRIVE OPERATION

This chapter describes the operation of the Spinpoint M8 hard disk drive functional subsystems. It is intended
as a guide to the operation of the drive, rather than a detailed theory of operation.

5.1 Head / Disk Assembly (HDA)

The Spinpoint M8 hard disk drive consists of a mechanical sub-assembly and a printed circuit board
assembly (PCBA), as shown in Figure 5-1. This section describes the mechanism of the drive.

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 base casting assembly (which
includes  the  DC  spindle  motor  assembly),  the  disk  stack  assembly,  the  head  stack  assembly,  and  the  rotary
voice  coil  motor  assembly  (which  includes  the  actuator  latch  assembly).     The  HDA  is  assembled  in  a  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.

The  Spinpoint  M8  hard  disk  drive  models  and  capacities  are  distinguished  by  the  number  of  heads  and
disks.  The  ST320LM001  have  one  (1)  disk  and two  (2)  read/write  heads.  The  ST500LM012  has  one  (1)  disk
and  two  (2)  heads.    The  ST750LM022  have  two  (2)  disks  and  t h r e e / four  (3/4)  read/write  heads.  The
ST1000LM024 has two (2) disks and four (4) read/write heads.

5.1.1 Base Casting Assembly

A one piece, aluminum-alloy base casting provides a mounting surface for the drive mechanism and PCBA.
The base casting also serves 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.

5.1.2 DC Spindle Motor Assembly

The   DC   spindle   motor   assembly   consists   of   the   brush-less   three-phase   motor,   spindle   bearing   (FDB)
assembly,    disk    mounting    hub,    and    a    labyrinth    seal.    The  entire  spindle  mo to r  assembl y  is
completely  enclosed  in  the  HDA  and  integrated  to  the  base  casting.     The  labyrinth  seal  prevents  bearing
lubricant from coming out into the HDA.   The motor rotates the spindle shaft at 5400 rpm.
