Abstract

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 actuator arms embedding part of the magnetic proximity latch, actuators, and disk drives using the crash stop and proximity latch, as well as methods of making actuator arms, actuators and disk drives.
