摘要： An information readout apparatus and an information readout method can efficiently correct the change in the size of the aperture. An optical disk 1 having a recording layer and a readout layer is used and the information recorded on the recording layer of the optical disk 1 is read out by irradiating a light beam onto the optical disk form head 2 and opening a detection window smaller than the area irradiated by the light beam in the readout layer. The resolution detecting section 15 of the apparatus detects the isolated mark recorded in the optical disk 1 in advance and then detects the resolution on the basis of the quotient obtained by dividing the difference X between the sample value Y near the peak of said isolated mark and the sample value adjacent to said sample value Y by said sample value Y near the peak, or X/Y. The readout control circuit 14 of the apparatus controls the size of the detection window so as to make the resolution detected by the resolution detecting section 15 close to the reference value K from the reference value output section 13 of the apparatus.

摘要： A phase error detection apparatus and method is disclosed whereby a data signal is played back at a high S/N ratio from a magneto-optical disk making use of a ghost signal by magnetic domain wall displacement detection while the playback laser poser is kept at an optimum level. First, the laser power is controlled so that the time delay of a ghost signal from a data signal may be equal to a fixed multiple of a data detection clock. Thereupon, a laser power control section searches for a point at which the amount of jitters generated is small based on a RF signal. Then, the playback laser power is adjusted so that the time delay amount of the ghost signal from the data signal may be the fixed multiple n=5 of the clock nearest to the phase delay amount set in advance of a ghost which appears in the isothermal region with a laser power with which an optimum signal characteristic is obtained. In this instance, the laser power control section searches for a peak of the 5T amplitude of the displacement phase difference controlling pattern.

摘要： An optical information recording medium, an optical information recording method and an optical information recording apparatus are able to prevent one laser beam of two laser beams from affecting the other laser beam by an offset. In an optical disc in which a groove whose one-side is wobbled or modulated only is sequentially formed by turning on or off one laser beam of two laser beams in accordance with a modulation signal and desired data is recorded by the groove, since the groove is formed by wobbling the one laser beam in such a manner that the one laser beam may not affect the other laser beam, a light intensity of the one laser beam is not added to a light intensity of the other laser beam, which is not wobbled by a wobbled amount so that the other-side of groove may be protected from the influence of the offset.

In a second method, in a recordable and reproduceable area, a land/groove-alternate track structure is configured such that grooves become data recording tracks in the circular track next to the circular track in which lands become data recording tracks, and lands become data recording tracks in the next circular track. In the read-only area, pits are arrayed such that tracks in the radial direction of the disk are formed in the data area.
