Abstract
Radial access apparatus for controlling the coarse and fine radial position of a read/write head relative to a data storage disk (e.g. optical, magneto-optical and magnetic disks) comprises a radial access arm supported for movement about a virtual pivot point by a pair of converging flexure members. An electromagnetic motor is provided for controlling the position of the arm to position a read/write head, supported by such arm, opposite a desired data track on the disk.
