摘要： A disc player having a prepit detecting circuit which can correctly detect prepits even if phases or amplitude levels of a plurality of read signals read out from a recording disc are deviated from each other. A phase difference between a first read signal and a second read signal read out by first and second reading elements arranged in two regions divided along the direction of recording tracks of a recording disc is detected. A first phase correction read signal is obtained by adjusting the phase of the first read signal by an amount according to the phase difference. A differential value between the first phase correction read signal and the second read signal is outputted as a prepit detection signal.

摘要： A disc type identifying system for efficiently identifying one optical disc type from others having different recording formats, though having the same size and shape, is provided. The disc type identifying system comprises driver for rotating a disc to be identified a predetermined number of rotations; frequency detector for detecting frequency of a playback signal from the disc to be identified; and identifier for identifying the disc type based on the frequency of the playback signal detected when the disc to be identified is rotated the predetermined number of rotations. The predetermined number of rotations is set at the lowest linear speed among linear speeds defined in the different recording formats. Because the disc type may be identified in the process of a startup operation of a combination unit by constructing as described above, the startup time may be shortened, thus enhancing the efficiency of the system.
