Abstract
An actuator latch cooperating with a magnetic assembly for latching an actuator assembly of a data storage device is provided. The magnetic assembly includes a magnet secured to one of a pair of pole pieces. The actuator latch includes a latch body adjacent the magnet assembly; a forward arm extending in a first direction from the latch body, a first ferromagnetic member supported by the forward arm disposed between the pair of pole pieces interacting with the magnet to maintain the actuator assembly in an un-latched position during operation of the data storage device; a trailing arm extending in a second direction from the latch body; and a pair of ferromagnetic members supported by the trailing arm disposed between the pair of pole pieces interacting with the magnet to secure the actuator assembly in a latched position during non-operation of the data storage device.
