Abstract: A method of and a circuit for providing a playback signal, which is compensated for time delay, from a photodetector having a plurality of outputs. A time difference between a first signal corresponding to a part of the outputs of the photodetector and a second signal corresponding to another part of the outputs of the photodetector is detected and one of the first and second signals is temporally shifted to compensate for a time delay between different outputs of the photodetector. The temporally shifted signal is summed with the other signal to provide a playback signal. Accordingly, the time delay between the outputs of the photodetector is compensated, thereby increasing the degree of modulation of the data playback signal. In addition, distortion or degradation of the signal is suppressed and occurrence of errors in the playback signal is minimized, thereby improving the reliability of the playback signal.

Abstract: A physical identification data (PID) addressing method using a wobble signal, a wobble address encoding circuit, a method and circuit for detecting the wobble address and a recording medium therefor. Groove address information indicating physical identification information is phase modulated using a wobble clock signal and recorded in one of the two walls of a groove track, and land address information is phase modulated using a wobble clock signal obtained by shifting the phase of the former wobble clock signal and recorded in the other wall. That is, address information is phase modulated and recorded in each track using the wobbles having a phase difference of 90° between adjacent tracks so that a sum of wobble signals from the adjacent tracks can be a quadrature phase shift keying (QPSK) signal. Therefore, more data can be recorded in the recording medium, and since an interval in which a wobble signal disappears is not caused, recovery of a wobble clock signal can be advantageously performed.

Abstract: A physical identification data (PID) addressing method using a wobble signal, a wobble address encoding circuit, a method and circuit for detecting the wobble address and a recording medium therefor. A wobble signal obtained by phase modulating address information indicating the physical identification information and a wobble signal having only a simple carrier are recorded in each groove track by way of time division multiplexing. Groove tracks are divided into odd groove tracks and even groove tracks, and a wobble carrier and wobble address information are alternately recorded in each groove track and between odd and even groove tracks such that the wobble address information is not recorded in a section of an even groove track corresponding to a section of an odd groove track in which the wobble address information is recorded. Therefore, interference between wobble signals of adjacent tracks can be removed, and a method and a circuit for detecting a wobble address can be simplified.

Abstract: An optical recording medium and a recording/reproducing method therefor to stably and accurately address a basic recording and/or reproducing unit (a sector or a frame) when a track pitch is decreased for recording of a large capacity of data. The general information (e.g., a variable frequency oscillator, a sector number, a sector type, and error detection information) of a corresponding sector is read from a header, which has physical pits between adjacent land and/or groove tracks, before recording or reproducing. The arrangement of the header is in the form of physical pits, with a sector structure where 2-kilobyte minimum recording units are included in a user area within a basic recording unit of 4 kilobytes, which thereby reduces overhead and facilitates the generation of a servo control signal.
