摘要： Even if grooves are, in order to improve productivity, omitted from an optical recording medium having pits indicating information signals formed in at least a portion of recording tracks of the optical recording medium, signals having satisfactorily high levels required to perform tracking control are attempted to be obtained. The number of regions of the recording tracks in which the pits are formed is made to be larger than the number of regions in which no pit is formed. Specifically, since "0" has higher appearance probability than "1" in a case of a binary information signal consisting of "0" and "1", pits are formed at positions corresponding to "0" of the information signal.

摘要： At the boundary between the program area and the recording area, buffering areas where no valid data exists are respectively provided in the program area and the recording area. These respective buffering areas are caused to be access inhibit area, and neither recording or reproduction is carried out in these areas. For this reason, oscillation of the tracking servo which is likely to take place when light spot is passed through the boundary between the program area and the recording area is suppressed to realize tracking servo stable at all times. Thus, temporary missing of information signals is prevented.

摘要： The stable reproduction of wobble signal without generating beats despite of an improvement in recording density by narrowing a track pitch is realized. Data by magnetooptical recording is recorded on wobbling grooves and lands between adjacent wobbling grooves. The wobbling grooves are provided to wobble both sides of the grooves in different amplitudes. Further, both the sides wobbled in different amplitudes are wobbled in phase in the track direction. These different amplitudes of both sides are preferably set to 3.3 to 40%.

摘要： In an optical recording medium having a writable area in which grooves are formed along recording tracks and a read-only area in which pits are formed along the recording tracks, sufficient levels of signals required for data write and read can be assured even with the track pitch reduced for a higher recording density. Assuming that the refractive index of a medium provided extending from a light-incident surface to a surface in which the grooves and pits are formed is n and the wavelength of a light used for data write and read is &lgr;, the grooves and pits has a width within a range of &lgr;/7.5 n to &lgr;/6. On the assumption that the width of each of the grooves formed in the writable area is Wg and the pitch between the recording tracks in the writable area is Tp1, Wg/Tp1 is within a range of 18.4% to 31.1%. When it is assumed that the width of each of the pitches formed in the read-only area is Wp and the pitch between the recording tracks in the read-only area is Tp2, Wp/Tp2 is within a range of 35.7% to 44.3%.

摘要： A method for measuring a deviation between the centerline between grooves defined on both sides of a recording track of an optical disc of a sample servo tracking system and a control prepit pattern formed on the disc is disclosed. If the modulation indices of the wobbled pits are measured under continuous tracking control of the center region or land, a difference is produced in the modulation indices when there is a deviation between the center of the wobbled pits and the center of the grooves. If, under tracking control of the grooves, the tracking offset is adjusted so that the modulation indices of the wobbled pits are equal to each other, the tracking error signal has an offset quantity (DC component). A light beam is swept under tracking control of the land between the grooves and the deviation between the center of the grooves and the control prepit pattern is measured. The light beam is swept so that the playback outputs from the wobbles pits are equal to each other and the deviation between the control prepit pattern and the center of the grooves is measured by a tracking error signal of the land between the grooves.

摘要： Binary information previously recorded in an innermost rim side area is enabled to be stably reproduced. A record medium is formed by sequentially laminating a first information layer 2, an intermediate layer 3, a second information layer 4, and a cover layer 5 onto a substrate 1. First grooves are previously formed in the innermost rim area of the substrate 1. Second grooves are previously formed in an area where data is recorded. The first grooves are set to be shallower and narrower than the second grooves. Thus, such a situation that a BCA signal is modulated by diffraction due to the grooves can be reduced.
