    摘要： An ultra-small optical/magnetic head actuator includes: a swing arm movable in a horizontal direction (tracking direction) and a vertical direction (focusing direction) and having mounted thereon a head for reading and writing information on a disk. A tracking actuator moves the swing arm in the horizontal direction (tracking direction) and a pivot hinge adjusts a radius of rotation of the swing arm and guides the movement of the swing arm in the tracking direction. A focusing actuator moves the swing arm in the vertical direction (focusing direction), wherein the focusing actuator includes a focusing coil attached under the swing arm and a Halbach magnet array disposed under the focusing coil minimizes thickness. Friction or backlash can be avoided, and non-repetitive errors can be reduced. The thickness of the ultra-small storage device can be reduced due to the use of a Halbach magnet array.

    摘要： A recording layer of a magneto-optical storage medium having a sublayer in accordance with the present invention comprises a recording layer on which information is recorded and stored; and a sublayer formed above or below the recording layer and made up of an alloy containing a transition metal, wherein a magnetic anisotropy energy of the sublayer is exchange-coupled to the recording layer, thereby enhancing a coercive force of the recording layer. The sublayer may be formed in a single-layered structure having one layer, or in a multi-layered structure having a plurality of layers. The sublayer is preferably made up of an alloy containing a transition metal used for the recording layer. According to the present invention, the coercive force of the recording layer can be increased by an exchange coupling effect between the recording layer and its adjacent sublayer, and thus, the stability of the magnetic domain in the recording layer can be improved. Therefore, the size of the magnetic domain can be significantly reduced, and the density of recording can be increased.

    摘要： Provided is a small form factor optical/magnetic disk including an integrated metal hub and a disk plate. The integrated metal hub includes a circular upper metal hub and a circular lower metal hub integrally formed with and disposed under the upper metal hub. The circular lower metal hub has a smaller diameter smaller than the upper metal hub. A central hole is formed in central portions of the upper and lower metal hubs and passes through the upper and lower metal hubs. The disk plate has a through-hole that is formed in a central portion and is directly associated with the integrated metal hub, and a recess that is formed around the through-hole and allows the upper metal hub to be mounted therein. Since the central portion of the small form factor optical/magnetic disk is not thick, the small form factor optical/magnetic disk can contribute to an ultra thin small form factor information storage device. Also, since manufacturing processes are simple, price and quality competitiveness can be enhanced.
