    摘要： An optical disk includes tracks and grooves, the grooves being formed with a pitch equal to or greater than about λ/NA. A first array of pits is provided at a position which is shifted by a predetermined amount with respect to each track in one of two directions substantially perpendicular to the tracks, the first array of pits being formed with a predetermined pitch, where the predetermined pitch is a function of a pitch of the grooves taking a value within a range from about 0 to about λ/NA. A second array of pits is provided at a position which is shifted by a predetermined amount with respect to the track in the other one of the two directions substantially perpendicular to the tracks, the second array of pits being formed with a predetermined pitch, where the predetermined pitch is a function of the pitch of the grooves taking a value within the range from about 0 to about λ/NA. λ is a wavelength of a light beam which is radiated on the optical disk, and NA is a numerical aperture of a lens.

    摘要： An information recording method has;

    a history determination step for determining whether or not a medium being cased and capable of being used for information recording and reproducing ,has previously been taken out from the case by using an identification section having historical information as to whether the medium has previously been taken out from the case or not ;and
    when a result of the determination shows that the medium has previously been taken out from the case ,

    for verifying correctness of information after recorded or recording after verification of correctness of information always or on condition that a predetermined condition is satisfied ,or inhibiting the recording , if the medium is a first recording/reproducing information medium that is required to use a case at recording ,and
    for recording normally if the medium is a second recording/reproducing information medium that is not required to use a case at recording.

    摘要： An optical data recording method comprising the steps of: modulating data to be recorded, to generate a plurality of recording modulation codes, and emitting a pulsed light beam to an optical disc, so that predefined and selectable recording marks and spaces are recorded on the disc, the lengths of the recording marks and spaces being defined by the modulated data, wherein at least two of the plurality of the recording marks comprise: a first pulse which is disposed at the front and forms the leading edge of the recording mark; a last pulse which is disposed at the backend and forms the trailing edge of the recording mark; and a multi-pulse train which is disposed between the first pulse and the last pulse and forms the center of the recording mark, the multi-pulse train having a pulse period longer than T, T representing a reference period of the recording modulation code; the number of pulses in each of the recording marks is increased by one as the recording mark is increased in length by 2T, characterized in that the recording marks have different lengths differing by T or multiples thereof, and the shortest recording mark and the second shortest recording mark are constituted by a single pulse, and a corresponding device.

    摘要： An optical disk device comprising a converging optical system (21) in which a laser beam (5) is irradiated onto an optical disk (1) having a recording thin film on a substrate provided with uneven guide grooves (4) and a tracking controller (12) that controls tracking so that the laser beam converged by the converging optical system scans a convex part or a concave part of the guide groove, wherein the tracking controller controls tracking polarity so that the tracking polarity is inverted according to the depth of the guide groove. As a result, in optical disks having any groove depth, a laser beam can scan a target groove track or a target land groove track correctly.
