ABSTRACT:
A disc drive magnetic latch includes a magnet, a bucking coil, and a pair of pole pieces in a housing. The pole pieces have rectangular extension which extend through fingers in the housing thereby locking the pole pieces against rotational movement when a striker on the actuator strikes them. Heat staked tabs hold the assembly together.
