ABSTRACT:
A two and one half inch form factor disk drive has a metallic base and a metallic cover to enhance the rigidity of these components with respect to plastic components. The sealing of a controlled environment established between the base and cover is enhanced by the increased rigidity of the base and by providing a gasket groove in the base and a gasket having a tongue which mates with the groove. In addition, the metal base and cover provide isolation from the noisy environment of a computer. The two and one half inch form factor is established by providing the disk drive with a length equal to the width of a 31/2 inch disk drive and a width equal to half of the length of a 31/2 inch disk drive. The disk drive includes a disk having a diameter of approximately 2.6 inches (65 mm) and weighs approximately 6 ounces. A closed-loop, embedded servo tracking system provides a large storage capacity relative to the area of storage media available.
