    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: The present invention relates to an apparatus for measuring a slant angle in a solid immersion lens. In a near-field optical data storage head for storing/reading data using a solid immersion lens (SIL), a parallel light is formed within the plane of the solid immersion lens and the slant angle of the parallel light is then measured using the angle measurement principle of the autocollimator in order to measure the slant angle of the solid immersion lens. For this, the present invention includes an optical system for generating the parallel light within the solid immersion lens, and a unit for measuring the slant angle of the solid immersion lens using a location detection unit. An incident light becomes the parallel light by the optical system and the curved face of the solid immersion lens. The reflected light is also focused on the location detection unit. The location detection unit converts the reflection angle of the reflecting light into a location value to calculate the angle value.
