摘要： A method for recognizing at least two types of optical discs, which are associated with multiple different numerical apertures, includes the step of setting the numerical aperture of a focusing mechanism equal to a first one of the multiple different numerical apertures. The focusing mechanism is used to focus a light beam on a data storage layer of a given optical disc. The first numerical aperture is smaller than any of the other numerical apertures. The method further includes the step of recognizing the type of the given optical disc by the first numerical aperture that has been selected in the step of setting the numerical aperture.

摘要： To improve a precision of tracking control. A tracking control apparatus includes a filter section (106) including a plurality of low-pass filters (LPFs). Each of the plurality of low-pass filters (LPFs) removes components having frequencies equal to or higher than a predetermined cutoff frequency from a corresponding received light quantity signal among a plurality of received light quantity signals output from light detection means (6). The tracking control apparatus includes: a tracking error detection section (104) for generating a tracking error signal indicating an amount of deviation of an optical beam spot from a track to be scanned on a recording surface of an optical disc by performing predetermined calculations with respect to a plurality of signals output from the filter section (106); and a tracking control section (102) for driving moving means (101) such that the optical beam spot follows the track on the recording surface of the optical disc in accordance with the tracking error signal.

摘要： An optical disc drive is used to read and/or write data from/on an optical disc having a data storage layer. The drive corrects electrical offset while reading and/or writing data. The drive updates a correction value based on an electrical offset detected at correcting operation or a value derived using electrical offset values that has been detected and stored, without detecting an electrical offset at correcting operation. Therefore, the optical disc drive can correct the electrical offset less often.

摘要： An optical disc has a plurality of sectors, where each of the plurality of sectors includes a plurality of frames. A sub information bit value of “0” or “1” is assigned to the plurality of frames constituting a sector, excluding the first and last frames. Edge positions are displaced so that leading/lagging errors appear in accordance with a certain rule when data fields of the frames to which the sub information bit value “1” is assigned are read. Edge positions are displaced so that leading/lagging errors appear in accordance with a reversal of the certain rule when data fields of the frames to which the sub information bit value “0” is assigned are read.
