Abstract
A magnetic disk apparatus includes a first disk drive unit capable of accessing a first-size disk contained in a first disk cartridge, and a second disk drive unit capable of accessing a smaller, second-size disk contained in a second disk cartridge, the second disk drive unit being attached to the first disk drive unit to form a single unit. The second disk drive unit comprises: a chassis having a size substantially equal to a size of the first disk drive unit; a disk motor which rotates the second-size disk of the second disk cartridge on the disk motor when the second-size disk is accessed; and a motor base attached to a bottom of the disk motor, the motor base including a control circuit to control the rotation of the disk motor. An entire top area of the first disk drive unit is covered with the chassis of the second disk drive unit, and an entire height of the second disk drive unit is substantially equal to an entire height of a conventional disk drive unit added to a thickness of a top plate.
