ABSTRACT:
A magnetic disk drive apparatus includes a base plate and a first motor mounted on the base plate. The first motor has a rotatable shaft engageable with a magnetic disk for rotating the magnetic disk. A carrier has a central opening through which the shaft of the first motor extends. A magnetic head fixed to the carrier is engageable with the magnetic disk. Opposite sides of the carrier is slidably supported on the base plate. A second motor mounted on the base plate has a rotatable shaft. The carrier and the shaft of the second motor are coupled so that the carrier slides linearly in accordance with rotation of the shaft of the second motor.
