Abstract
A disk drive includes an inner frame that has a disk drive base and a disk drive cover. A disk, mounted on a rotary spindle attached to the disk drive base, defines a disk outer periphery that protrudes into a first side opening of the inner frame. A head actuator is attached to the disk drive base and to the disk drive cover. An outer enclosure includes an extruded hollow cylinder with a cross-sectional shape that is a continuous and unbroken ring that is substantially rectangular, and that surrounds a cavity. The outer enclosure surrounds the disk drive base and the disk drive cover. During assembly, the inner frame may be slid lengthwise into an open end of the outer enclosure, and the outer enclosure may be hermetically sealed to enclose air or helium in the cavity.
