Abstract
A hard disk drive implemented as a plug-in module has a height of 10 mm and a foot print of 85.6 mm.times.54 mm. The footprint corresponds to the dimensions of memory cards. The disk drive uses a modified suspension in which the load beams are welded to actuator plates, thereby eliminating the use of a stakable suspension. The disk may be a glass substrate having a thickness of approximately 0.381 mm (0.015") or an aluminum substrate having a thickness of approximately 0.635 mm (0.025").
