Abstract
Disclosed herein is a disk drive that includes a housing including a base, the base defining a blind receptacle, a spindle motor attached to the base, a disk mounted to the spindle motor and a head stack assembly pivotally coupled to the base. The head stack assembly includes a body portion including a first bore defining a pivot axis, an actuator arm cantilevered from the body portion, and a head gimbal assembly supported at the actuator arm and including a head. The base defines a blind receptacle and the actuator arm defines a second bore that is situated so as to enable the second bore and the blind receptacle to align along an axis parallel to the pivot axis when the head stack assembly is pivoted such that the head is not over the disk.
