    • An optical disc is disclosed having a substrate in which data can be written on or read from, such optical disc has a transparent cover sheet which is held at a desired spacing from the substrate at least at an inner radius and an outer radius. In order to prevent the transparent cover sheet from deflecting due to pressure differences between the outside atmosphere and the air in the space between the substrate surface and the transparent cover sheet, a plurality of air passages in the transparent cover sheet are provided near an inflection point where on one lateral side of the point the transparent sheet will bulge and on the other lateral side it will be depressed due to centrifugal force acting upon air entrapped between the transparent cover sheet and the substrate surface during disc rotation in an optical disc drive. This arrangement equalizes the pressure in the air space between the transparent cover sheet and the substrate surface and the outside atmosphere.

    • A focus/tracking actuator for an optical or magnetooptical disk drive includes a pair of moving-magnet type linear motors for simultaneously controlling the focus and tracking positions of an objective lens used to focus a write/read beam on a desired data track of a rotating data storage disk. Each motor includes a pair of selectively energizable focus and tracking coils, one coil being positioned within the other so that its respective windings are perpendicular to those of the other coil. Flux lines emanating from a permanent magnet secured to a movably mounted lens housing interact with the electromagnetic fields surrounding both coils, and a single steel plate or the like, positioned inside the windings of both coils, facilitates the return of magnetic flux to the magnet while preventing such flux from cutting portions of the coils which would act to exert an undesired forces on the lens housing. Preferably, the steel plate is composed of two segments to facilitate winding of the coils about the plate.

    • A low-profile radial access mechanism for controlling the radial position of a read/write head relative to a rotating data storage disk (e.g. optical, magneto-optical and magnetic disks). Such mechanism has a carriage (10) which supports a plurality of bearings (11) on its opposing sides. The bearings engage a pair of space parallel rods (21, 31) to guide the carriage along a rectilinear path. Each rod is made of a ferromagnetic material and forms part of the flux-carrying structure of one of a pair of separate electromagnetic linear motors (20, 30). One of the two flux-carrying structures is movable relative to the other to preload the bearings against the guide rods. According to a preferred embodiment, the pair of linear motors share the windings of a single coil (22) carried by the carriage, such windings being physically distributed as to accommodate an exact constraint arrangement provided by the bearings. Preferably, the bearings and coil are located and configured so that the center of mass of the carriage is located along the line of force exerted on the carriage by the linear motors.
