Hard Disk Drive Structure for Preventing Head Damage

      Disclosed is a Hard Disk Drive (HDD) structure for preventing
magnetic head damage during the HDD assembly process.  This is done
by making a boss and a sink on a base casting.

      In the HDD assembly process, an actuator is mounted onto a base
casting and then tied up with a screw.  Before fixing them, an
actuator is easily tilted with any external force, causing magnetic
head damage  by touching it to a base casting.

This structure solves this problem:
  Fig. 1 shows the top view of a base casting.
  Fig. 2 shows the top view and the side view of this structure.

      As shown in Fig. 2, a boss under the actuator-arm works as a
tilt-stopper.  If the actuator tilts, the sink under the magnetic
head keeps enough clearance between the magnetic head and the base
casting.
