ABSTRACT:
A disk drive head disk assembly having a compact configuration includes an actuator assembly mounted to a base plate through a three point mounting system. The actuator includes a voice coil which engages a magnet assembly having an integrated latch/magnet spacer including a fixed magnetic latch and cantilevered beam crash stop. A magnetic latch pin assembly mounted to the voice coil engages a permanent magnet employed in the fixed magnetic latch. The latch pin assembly includes a movable latch pin which has a degree of lateral movement which allows the latch pin to release from the permanent magnet with a consistent force.
