The invention includes an impact rebound crash stop pivoting about a pivot between the top and bottom yoke of an actuator magnet assembly. The impact rebound crash stop includes a latch bias tab magnetically attracted to the voice coil magnet when it is near. The invention further includes a proximity latch allowing the actuator to stay on the ramp when not in use. The invention includes the operation of actuator arms embedding part of the magnetic proximity latch, actuators, and disk drives using the crash stop and proximity latch.

Disk drive actuator impact rebound crash stop with bias tab and pusher and crash stop faces

A latch for securing an actuator arm of a hard disk drive. The latch has a catch portion that can engage a latch portion of the actuator arm. The latch also has a pusher portion and a crash stop portion that engage the actuator arm during movement into a latched position and prevent the latch from rebounding away from the arm. The pusher and crash stop portions eliminate the need for a separate crash stop in the disk drive. Eliminating the separate crash stop component reduces the complexity and cost for mass producing the disk drive.
