Abstract: A computer disk and audio compact disk holder includes an integral frame having a base and upright walls, the tops of said upright walls being substantially coplanar. A recess is defined by the base and upright walls, the recess being disposed below the tops of the upright walls and above the base. The walls are disposed such that they retain a computer disk or audio compact disk disposed in the recess in place therein. The frame further includes attachment structure for removably securing the frame to other structures or devices. The holder may be used to display a computer disk or audio compact disk for sale, as well as in combination with a storage system for storing a plurality of computer disks. The disk holder may be constructed to receive computer disks of three different sizes, the particular size used in a particular holder being at the discretion of the user.

Abstract: An electro-optical scanning device comprises a lens (2) having an optical axis (2a), which lens is movable in a focusing direction (F), related to the optical axis, to form at least one radiation spot on a surface to be scanned, and in a tracking direction (T), oriented transversely of the focusing direction, to follow a recording track. The scanning device comprises a stationary section (16) having first actuator means and a movable section (6) having second actuator means, which movable section is movable relative the stationary section and carries said lens, which actuator means cooperate electromagnetically with one another via an air gap (20) in order to drive the lens. The movable section is secured to the stationary section by elastically deformable suspension means.

Abstract: An apparatus for linearly displacing a cartridge engaging assembly along a predetermined displacement path and for supporting the cartridge engaging assembly at a fixed orientation relative to its displacement path. The apparatus includes single or multiple elongate flexible members fixedly secured to the cartridge engaging assembly at at least three points thereon, a flexible member engagement assembly (e.g. pulleys) fixedly positioned relative to the displacement path, and a drive assembly operatively connected to at least one elongate flexible member.
