摘要： A hologram reproduced image position detecting method used in a hologram apparatus which perfoming an image formation with light reproduced from a recording medium where a data page including a marker and a data area that have been displayed on a spatial light modulator is recorded, on an image sensor having a larger number of pixels than the spatial light modulator, thereby obtaining a reproduced image of the data page to reproduce the data page. The detecting method comprises the steps of storing a template image into which the marker has been interpolation-expanded, beforehand; oversampling the reproduced image of the data page in the image sensor to obtain a detected image; and performing a template matching process on the detected image using the template image, thereby detecting the position of the marker when recorded.

摘要： A semiconductor laser driving device is mounted on an information recording/reproducing device or the like, and is suitably used for recording and reproducing information. The semiconductor laser driving device is provided with a semiconductor laser for emitting laser beams, and a temperature detecting means for detecting a temperature of the semiconductor laser, and changes an output of the laser beams based on the detected temperature. Thus, the semiconductor laser driving means can suitably improve response characteristics of the semiconductor laser, irrespective of the temperature of the semiconductor laser. Therefore, the semiconductor laser driving device can ensure recording performance to an optical disc without being affected by the temperature of the semiconductor laser.

摘要： In a two-dimensional probe array, an interval between the leading ends of probes adjacent to each other in an X direction is made shorter than that between the leading ends of probes adjacent to each other in a Y direction. Thus, the leading ends of the probes are arranged to form a lattice wherein many rectangles are arranged. Furthermore, the lowest resonance frequency of an actuator which moves a recording medium in the X direction is set higher than the lowest resonance frequency of an actuator which moves the recording medium in the Y direction. At the time of recording or reading information, the recording medium is reciprocated in the X direction at a frequency substantially equal to the lowest resonance frequency of the actuator.
