Abstract

A linear actuator carries read/write heads into engagement with a removable cartridge having a recording disk. The magnetic heads are mounted on a carriage which moves linearly on a central guide track. The carriage moves linearly on front and rear bearings which move on a central guide track as the magnetic motor is energized. The rear bearing is elongated in the direction perpendicular to the plane of the disk to allow movement of the carriage transverse to the direction of travel. This compensates for planar misalignment of the plane of the recording disk with respect to the axis of the central track.
