ABSTRACT:
A space efficient disk drive housing is described. The disk drive housing comprises a base member having a top, a bottom, and an outer perimeter having length and end portions of preselected dimensions and a cover element comprising a top surface and side walls depending downwardly from the top surface. The cover element has length and width dimensions corresponding to the dimensions of the length and end portions of the base member so that the cover element can be secured to the base member to form the housing. The cover element is provided with a first raised portion to provide a height dimension within the housing sufficient for topmost portions of a spindle motor and head stack assembly of a disk stack assembly of a disk drive. Remaining portions of the top surface of the cover element providing a continuous, single PCB support surface. A set of support posts is provided on the cover element of the disk drive housing. The support posts are used to mount the disk drive to a host computer. The spindle motor and head stack assembly are mounted to the base member. The removal of the support posts from the base housing element mounting the spindle motor and head stack assembly, as done in conventional disk drives, frees up space on the base to permit greater flexibility in the placement of mechanical components of the disk drive.
