A disk drive has an actuator supported for turning, and supporting magnetic heads for reading and writing data from and to a recording disk and a voice coil for driving the actuator. Plates are disposed near the voice coil so as to cover part of the voice coil. A hard disk drive capable of detachably combining with a PC card is formed by assembling separate component parts including a functional unit including a disk, a base plate holding the functional unit, a frame bumper disposed in a middle part of the assembly and serving as a shock-absorbing member, a card assembly provided with a connector to be connected to the slot of a PC card, and a top cover covering the functional unit held on the base plate. The frame bumper receives lateral shocks that act on the side surfaces of the hard disk drive.
