A two and one half inch form factor disk drive has a base and cover formed of molded plastic and engaged with each other by snap-fit connectors. The cover is molded from a plastic which is more flexible than that used for the base so that the cover complies to the base when the cover and base are engaged. Mounting brackets attached to the cover support a printed circuit board on the opposite side of the base from the cover. 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 5 ounces. A closed-loop, embedded servo tracking system provides a large storage capacity relative to the area of storage media available.
