ABSTRACT:
A magnetic latch for holding a head positioner assembly within a disc drive system. The disc drive system has a head positioning apparatus located within a housing for positioning a plurality of read/write heads relative to a recording media within the housing. The head positioning assembly carries a voice coil motor for precisely controlling the movements of the head positioner assembly. The magnetic latch is positioned within a bumper stop that limits the head positioners movement to hold the head positioner assembly in an orientation where the heads can be effectively parked without damaging the recording media.
