摘要： In optically coupling a plurality of light sources to an optical system for focusing light beams from the light sources into spots on a record plane, a center axis of a light beam from a first one of the light sources is aligned to an optical axis of the focusing optical system, and the spots other than a first spot formed by the light beam from the first light source are rotated around the first spot on the record plane to position the spots to the respective target tracks, and a tracking error signal for at least one of the first spot and another spot is detected and the positions of the plurality of spots are integrally controlled based on the detected tracking error signal so that the plurality of spots can follow the respective target tracks. The target tracks to which the spots are to be positioned may be either one track or different tracks. The positioning of the spots to the target tracks may be done either manually or automatically. In the automatic method, a tracking error signal is detected for the first spot, and a deflection mechanism for radially swinging beams from the laser light sources is controlled to control the positions of the spots on the record plane and to cause the first spot to follow the target track.

摘要： Method and apparatus for optically detecting information from a recording medium in which pits are formed by thermal energy of a light spot to record the information. A reproduction spot is irradiated onto the recording medium to produce a detection signal. From a differential signal of the detection signal, a signal indicative of zero points of the differential signal and a signal indicative of the presence of the pits are detected, and both the signals are used to detect positions of the pits. For stable and accurate detection of the pit position, the relation between pit size W and reproduction spot size W.sub.s is prescribed and the pit size and reproduction spot size are so set as to satisfy 0.45.ltoreq.W/W.sub.s .ltoreq.0.75.
