ABSTRACT:
A transducer head is located on a head arm. The head arm has a roller surface which contacts a fixed surface at a point of contact. The roller surface is attached to the fixed surface such that the roller surface may roll along the fixed surface without slipping. The roller surface and the fixed surface are such that a line between the point of contact and a disk center is always perpendicular to a line between the disk center and the transducer head for all positions as the roller surface rolls along the fixed surface.
