摘要： 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.

摘要： A disk drive unit has a spindle motor for rotating a disk, a magnetic head for processing data, a actuator for seeking the magnetic head with respect to the disk, a voice coil motor for moving the actuator, and a base with an opening and a top cover that seals the opening. A damper is disposed between the voice coil motor and the top cover. The voice coil motor comprises first and second yokes, which are placed opposite each other at a predetermined gap, and a permanent magnet disposed between the first and second yokes. The first and second yokes respectively have an inner perimeter edge facing the pivot axis, an outer perimeter edge facing the base, and a pair of side perimeter edges combining the outer and inner perimeter edges. The damper includes first dampers with a predetermined width along the pair of side perimeter edges.

摘要： A disk drive apparatus is constructed with a filter attached to an enclosure through a through hole formed in the enclosure. A special positioning operation is eliminated by inserting the filter into the through hole because a portion of the filter is exposed to the outside through the enclosure. The disk drive apparatus can be constructed so that the filter is supported on the enclosure. In this case, the enclosure has a chamfered portion around the circumference of the through hole; the filter has a flange corresponding to the chamfered portion; and the flange is brought into contact with the chamfered portion. The filter can be fixed to the enclosure by sticking adhesive tape on a circumference of the flange and a circumference of the chamfered portion of the enclosure. Adhesive residue is eliminated because the fixation of the filter is performed with single-coated tape.
