A disk drive has an enclosure that includes a first portion and a second portion that is configured to mate with the first portion. A spindle motor is attached to the first portion and a disk is mounted to the spindle motor. A head stack assembly is pivotally coupled to the second portion prior to the first and second portions being mated to one another. The head stack assembly includes a read write head that is configured to read from and write to the recording surface of the disk after the first and second portions are mated to one another.

Disk drive enabling simultaneous assembly of HSA and disk pack

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.
