1. A suspension assembly for holding a reading head within an operative distance from a surface of a spinning magnetic disk, said surface defining a disk surface, said magnetic disk including an outer edge and having an axis of rotation, said reading head being coupled to a moving arm by two resilient members, each resilient member being selected from the group consisting of a spring extension and a hinge,
said suspension assembly including purely mechanical means for causing said reading head to:
automatically move toward the disk outer edge when said disk surface moves away from said reading head; and to
automatically move toward the axis of rotation when said disk surface moves toward said reading head;
said resilient members being not rolled relative to the disk surface,
whereby track misregistration between said reading head and a data track on said magnetic disk is reduced.
