Attach the Cover for Flexible Cable to Protect Magnetic Head from
Destruct by Electrostatic Discharge at Hard Disk Drive

   Disclosed is a device for protect magnetic head in hard
disk drive from destruction by electrostatic discharge.  This device
covers electronic parts on flexible cable used to connect magnetic
head and interface card in hard disk drive.

   In hard disk drive, flexible cable connects magnetic head
and interface card to transmit signals.  If hand or other thing that
is electrostatic charged contacts or approaches for uncovered part of
circuit on flexible cable, it has the possibility that magnetic head
destruction by electrostatic discharge.  So, to attach the cover made
by nonconductive material for uncovered part of circuit, magnetic
head is protected from destruction by electrostatic discharge.

   In Fig. 1 there are uncovered parts of circuit on flexible
cable in hatched area.

   The flexible cable is assembled with a part with magnetic
head is shown in Fig. 2 In this condition, it has the possibility
that a magnetic head destruction by electrostatic discharged when
the part is dealt.

   The cover made by nonconductive material is attached
flexible cable to protect magnetic head from destruction by
electrostatic discharge is show in Fig.3
