Abstract
A method for manufacturing a disk drive includes assembling the head disk assembly in a clean room, performing servo writing upon the head disk assembly in the clean room, and performing a head disk assembly test upon the head disk assembly in the clean room. The head disk assembly is then connected to the controller printed circuit board assembly to form a drive-under-test. The drive-under-test is then transported to an integrated test system and electrically connected thereto. The integrated tests system then performs substantially all of the required manufacturing tests upon the drive-under-test, thereby substantially reducing the labor and floor space associated therewith.
