Abstract
Actuator apparatus is disclosed for positioning a plurality of magnetic heads transversely along a path which is substantially a radius of a rotating magnetic disc. The apparatus includes a parallelogram shaped supporting structure comprising a fixed inner member coupled to a movable outer member by a pair of resiliently deformable spring members. A suspension spring is mounted on the movable outer member and provides both gimbal support and pressure loading to a plurality of magnetic heads mounted thereon. The actuator apparaus further includes a continuous drive band affixed to the movable outer member and driven by a stepper motor for positioning the magnetic heads along the substantially radial path, thereby permitting information to be read from and written onto the various tracks of the magnetic disc.
