ABSTRACT:
A disk drive includes a disk, a latch assembly including a magnet and a head stack assembly for reading and writing to the disk. The head stack assembly includes a body portion defining a through bore that defines a pivot axis; an actuator arm cantilevered from the body portion; a head gimbal assembly coupled to the actuator arm; a coil portion cantilevered from the body portion in an opposite direction from the actuator arm, the coil portion defining first and second actuator fork members, one of the first and second actuator fork members defining a tang-supporting surface, the tang-supporting surface defining at least one cleating feature configured to increase a surface area of the tang-supporting surface, and a tang configured to interact with the magnet, the tang being attached to the tang-supporting surface by a layer of adhesive disposed on the tang-supporting surface.
