摘要： A hologram recorder/player includes recording beam modulation controller which causes a spatial light modulator to modulate the recording beam in such a way that a hologram is recorded in a plurality of blocks in a unit recording region and that each of the blocks includes recording information (DATA) and error correction code, at a time of recording. The hologram recorder/player includes incident angle variable controller which varies a reference beam incident angle to a plurality of predetermined angles with respect to the unit recording region. The recording beam modulation controller causes the modulation of the recording beam in such a way that a different hologram is generated for a page each time the reference beam incident angle is varied and that the hologram in each page is recorded in a plurality of the blocks.

摘要： An optical head includes a lens carrier movable at least radially of a magneto-optical disk in facing relation thereto. An object lens is mounted on the lens carrier to converge a laser beam for forming a laser spot on the disk. The object lens has an optical axis and includes a lens surface directed toward the disk. A patterned coil is formed on the lens surface at least in one layer and has a light-passing opening corresponding to the optical axis of the object lens. A light-pervious layer is formed on the lens surface for closing the light-passing opening of the coil.
