ABSTRACT:
A mechanism for accurately positioning a recording/playback head on the center of a track including a stepper motor and coil assembly in combination controlling coarse and fine transverse head position. The coil is attached to a pivoting actuator arm which provides a mounting member for a recording/playback head. A torsion spring is attached to the actuator arm and to a stage which is driven by a stepper motor lead screw to incrementally position the actuator arm. The coil assembly operates to pivot the recording/playback head transversely, thereby providing fine position control, and is mounted together with other members at either sides of a pivot axis to provide a dynamically balanced structure.
