Abstract
A compact card type disk drive includes a housing (21) for accommodating a disk for storing data, a disk drive for rotating the disk, a head assembly for writing and reading data to and from the disk and an electronic circuit including at least an interface circuit (39), the latter three being accommodated in the housing. A connector (42) connected to the electronic circuit is fixed to the outside portion of the housing (21). The electronic circuit preferably contains a read/write circuit (36) and a control circuit (38). The housing (21) preferably includes a lower base (22) and an upper cover (23), and a printed circuit board (14) is disposed along the inner wall of either one, or both, of the base (22) and the cover (23). The outer dimension of the plane of the disk drive is preferably about 85.6 mm.times.54 mm, and typically, the outer thickness is 5 mm. Preferably, one connector (42) is disposed on either one of the minor sides of the housing (21). The connector (42) is disposed at the substantial center of the housing in the direction of its thickness and is fixed to one of the minor sides of the housing (21) which opposes the head assembly with respect to the disk.
