摘要： 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.

摘要： An information storage medium and a method and apparatus recording data to the information storage medium, the information storage medium having a write pattern for recording data, the write pattern including at least one pulse and a number of the at least one pulse being determined depending on a length of a recording mark. This makes it possible to record data using a write pattern having an optimal number of pulses, thereby preventing degradation in jitter characteristics due to residual heat or heat build-up caused by the use of unnecessary pulses even during high speed recording.

摘要： A method of detecting a reproducing signal, and a circuit therefor. This circuit includes a detector, a control unit and a compensator. The detector detects the outputs of an optical detection device corresponding to a combination of signals corresponding to sections of the optical detection device arranged in the tangential direction, the outputs corresponding to a combination of signals corresponding to sections of the optical detection device arranged in the radial direction, and/or the outputs corresponding to a combination of signals corresponding to sections of the optical detection device arranged diagonally. The control unit provides a selection control signal and a compensation signal on the basis of the results of detection of the data conditions recorded on the optical recording medium, the interference between optical signals reflected/diffracted from pits in close proximity to each other and from adjacent tracks on a recording medium, and/or various system states. The compensator selects some of the outputs of the optical detection device provided via the detector in response to the selection control signal, and adaptively compensates for the selected outputs in response to the compensation signal. In this circuit, only some of the outputs of an optical detection device, which are the least degraded, are used as a reproducing signal, depending on the system states, the data conditions and/or the interference between optical signals reflected/diffracted from pits in close proximity and from adjacent tracks on a recording medium. Thus, the fitter of a detected signal is reduced, and the performance of the system can be improved.

摘要： 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.

摘要： 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.

摘要： A physical identification data (PID) addressing method using a wobble signal, a wobble address encoding circuit, method and circuit for detecting the wobble address and a recording medium therefor. When addressing physical identification information on a recording medium, which has land and groove tracks in which data can be recorded, using wobbles, a wobble signal obtained by phase modulating address information indicating the physical identification information and a wobble signal having only a carrier are repeatedly alternatively recorded on both walls of either of a groove track and a land track by way of time division multiplexing. Accordingly, land and groove addresses can be detected by the same method, and the land track can be easily discriminated from a groove track by making the sizes of the addresses different in the land and groove tracks.
