摘要： At the time of heterodyne detection, information is reproduced constantly in the optimum condition. A method reproduces information recording medium including a reference wobble block which has a first wobble pattern representing a first information content; and an information wobble block which follows the reference wobble block and which has at least one of the first wobble pattern and a second wobble pattern representing a second information and different from the first wobble pattern. The method includes reading the reference wobble block and the information wobble block; comparing a wobble pattern read from the information wobble block with the first wobble pattern of the reference wobble block; judging that information recorded in the information wobble block is the first information or the second information according to the wobble pattern read from the information wobble block; and outputting one of the first and the second information based on the judging result.

摘要： A method for reading address information from an optical disc with a wobbled track groove includes the steps of: obtaining a sine wave address signal, a first address signal representing a first groove region with sine wave wobbled portions and an inverted phase portion, and a second address signal representing a second groove region with steep inward or outward displacements; multiplying a first reference signal, being phase-locked to, and having the same frequency as, the sine wave address signal, and the first address signal together to obtain a first multiplied signal; multiplying a second reference signal, being phase-locked to, and having a frequency twice as high as, the sine wave address signal, and the second address signal together to obtain a second multiplied signal; integrating the first, multiplied signal and the second multiplied signal separately to obtain a first integral and a second integral, respectively; and adding the first and second integrals together.

摘要： The S/N ratio is improved for recording data to grooves (2-1,2-2) of an optical disc so that as much information as possible can be recorded at the lowest possible frequency band. An optical disc using wobble patterns to record different information has a first groove (2-1) having a first wobble pattern (22) in which one wobble period has a sharp rising edge and a gradual falling edge; and a second groove (2-2) having a second wobble pattern (24) in which one wobble period has a gradual rising edge and a sharp falling edge. Each of the first and the second wobble pattern is represented by a first fundamental and a second harmonic of a Fourier series. The polarity of the second harmonic, which is an even harmonic, of the second wobble pattern is opposite that of the first wobble pattern. A method for manufacturing this optical disc is also provided.

摘要： An optical disc playback apparatus capable of signal processing so that the above-noted new jitter does not appear even when a waveform equalizer is used is provided. A trimmer is inserted before the waveform equalizer, the maximum amplitude in the positive direction of the playback signal waveform and the maximum amplitude in the negative direction are limited so that amplitude in the positive direction and amplitude in the negative direction are substantially equal. Jitter in the playback signal can be improved as a result.

摘要： An apparatus for reproducing information that has been digitally recorded on a storage medium includes first and second waveform equalizers. The first waveform equalizer equalizes a read signal, corresponding to the information read out from the storage medium, thereby outputting a first equalized signal. The second waveform equalizer has an equalization characteristic different from that of the first waveform equalizer, outputs a second equalized signal and is selectively used to extract a read clock signal.

摘要： If data is recorded using a disc with deviating characteristics and a recorder with deviating characteristics, data will not be appropriately recorded, and errors will occur in the read signal. Standard recording pulse parameters specifying recording pulse positions for plural possible mark length and space length combinations are read from a writable optical disc, these standard recording pulse parameters are then used for test writing, the standard recording pulse parameters are changed uniformly or individually, a best recording pulse parameter is thus obtained, and jitter can be reduced.

摘要： When data is reproduced by an apparatus which is different from an apparatus used for recording the data, the fluctuation of edge positions of the reproducing data increases, making reproduction incompatible, and the present invention solves this problem. The present invention comprises reproducing learning means 13 and 24 for switching a frequency characteristic of the reproducing system, which detects the changes of the local optical constant, to a predetermined frequency characteristic, and recording learning means 20 for correcting the start edge or end edge position of the recording pulse for each combination of length of a mark block and length of the preceding or subsequent space, so that the edge position of the binarized reproducing data comes to a desired position, and since the frequency characteristic of the reproducing system is unified before learning the edge shift amount caused by the thermal interference between marks, the length of the recorded marks and spaces can always be constant, which improves the reproducing compatibility among reproducing apparatuses.
