摘要： An optical head device includes a light source for emitting at least one of a coherent beam and a quasi-monochromatic beam; a collection optical system for collecting the beam to an information memory medium having a track which has at least one mark and at least one space; a light detector having a plurality of detection areas for receiving the beam reflected by the information memory medium and outputting a signal in accordance with a light amount of the beam received; and a tracking error signal generator for receiving the signals output from the light detector and generating a tracking error signal based on the signals. The tracking error signal generator reduces a difference between a first signal amplitude and a second signal amplitude. The first signal amplitude is an absolute value of a difference between first and second signal levels. The second signal amplitude is an absolute value of a difference between the first and third signal levels. The first signal level is a value of the tracking error signal obtained when the beam emitted by the light source is radiated to a center of the track. The second and third signal levels are, respectively, a maximum value and a minimum value of the tracking error signal obtained when the information memory medium is scanned by the beam emitted by the light source in a direction perpendicular to the track.

摘要： A multiplexed holographic recording apparatus records multiplexed holograms in a plurality of recording regions that are formed on a holographic recording medium. In particular, the apparatus first records a predetermined number of multiplexed holograms in each of the recording regions formed in a predetermined range or an overall range of the holographic recording medium through holographic recording performed N times, and then performs the (N+1)th holographic recording in each recording region formed in the predetermined range or the overall range. When n other recording regions (where n=0, 1, 2, . . . ) are superimposed on each recording region formed on the holographic recording medium, a difference in the degree of multiplexing between the recording regions formed in the predetermined range or the overall range of the holographic recording medium does not exceed a predetermined value of n+1.
