Non-Volatiled Memory on Actuator

      Disclosed is a method to use Non-Volatiled Memory on Flex Cable
of Actuator in a Hard Disk Drive for the management/control of
quality, part inventory and technical information below:
  1.  Traceability Purpose
      a.  Actuator Serial Number
      b.  Actuator Manufactured Date
  2.  Quality Control/Failure Analysis Purpose
      a.  Each Components Characteristic Data
      b.  Actuator Manufacturing Quality Data/Parametric Data
  3.  Parts Inventory/Production Control Purpose
      a.  Each Components Parts Number/Engineering Information
      b.  Each Components Quantity used.

      Current methods like a Stamp or a Bar-Code Label don't have
enough space to provide all the information above or needs Host
Computer (or Server Personal Computer (PC)) to control all of them.

      By using Non-Volatiled IC Memory Built-In Read/Write Pre-AMP
(AE Module) on Flex Cable, all the information can be stored in it
and the read/write operation of those data is done through a system
interface easily.  This method can handle a tremendous amount of
information without any Server PC/Net-Work support.  In another
words, Actuator carries all the information needed.
