Abstract
A disk drive crash stop/actuator latch combines a crash stop structure with a detent actuator latch which is engaged and latched in a selected radial limit position of the actuator and which is released by the simple expedient of pulsing the actuator motor. The detent actuator latch has a flexible cantilever latch arm secured at one end to the disk drive base. A crash stop face on the distal end of the cantilever latch arm is impacted by a surface on a catch member on the actuator in the radial limit. The cantilever latch arm is bowed between its ends to reduce long column stability to slightly yield to compression loads due to actuator impact. The crash stop face and the surface of the catch member on the actuator are in contact when the detent actuator latch is engaged. A pulse generator coupled to the actuator motor pulses the actuator motor in a sense to drive the actuator away from the crash stop face, overcoming the restraining force of the engaged detent actuator latch.
