    摘要: When an optical disc apparatus reproduces information from an optical disc, it converges a reading light beam emitted from an LED to substantially collimated light and projects it to the optical disc to cause it to be reflected by reflection surface thereof so as to make it become a reading reflected light beam. Then, the apparatus converges the reading reflected light beam by a mark layer selection lens, detects the reading reflected light beam passing through the target position by a detection region located at the confocal point of the target position and generates a detection signal. Subsequently, the apparatus recognizes the presence or absence of a recording mark based on the detection signal to reproduce the information. Thus, the apparatus can detect the state of the reading reflected light beam observed when it passes the target position and can recognize the presence or absence of a recording mark.

    摘要: Disclosed is an optical disc device that is able to increase accuracy in reproducing information from an optical disc. The optical disc device 10 calculates a focus error signal SFE2 and a sum signal SS1 while reciprocating an objective lens 21 in a focus direction until a distance between a focal point FS and a focal point FM1 becomes close to the depth d of a target position PG at the time of a pull-in operation, and when a trigger signal ST1 generated on the basis of the sum signal SS1 is at low level, starts focus control on the basis of the focus error signal SFE2. Therefore, focus control can start in a state where the focus error signal SFE2 curves in an S shape with sufficient amplitude.

    摘要: A hologram device records information of an interference fringe of signal light and reference light onto a hologram recording medium and reproduces the recorded information by emitting the reference light onto a recording area of the hologram recording medium. The hologram device includes a recording/reproducing controller performing a recording operation of the information concurrently with a reproducing operation of previously-recorded information, and an error detector detecting an error in the previously-recorded information reproduced concurrently with the recording operation.
