    摘要： The width W of the address pit (9) of an optical recording medium of intermediate address type is determined by W=k Tp/(λ/NA) where λ is the laser wavelength of the optical head of the optical disk device use, NA is the numerical aperture of the objective, Tp is the track pitch of the record medium, and k is 0.40≦k≦0.68. Alternatively, an optical device comprises a first address demodulating circuit for demodulating address information by using a signal that is the sum of the electric signals outputted from a pair of photodetectors separated in the direction of the track and a second address demodulating circuit for demodulating address information by suing a signal that is the difference between the electric signals. The address is detected base on the information thus obtained. In such a way, the compatibility of the recording medium used and that of the optical device are improved, the reproduction margin in demodulating the address information is increased, realizing high accuracy address detection when reproducing data from an optical recorded medium of intermediate address type.

    摘要： An optical information recording medium includes: a substantially disk-shaped substrate; and a recording layer formed on a surface of the substrate for recording, reproducing and erasing information by irradiation with a laser beam. A test recording region for test recording and an information recording region for recording the information at least are arranged on the surface of the substrate. In the test recording region and the information recording region arranged on the surface of the substrate, a test recording track and an information recording track respectively are formed in a spiral-shaped arrangement or in a concentric arrangement. A track pitch of the test recording track is wider than a track pitch of the information recording track.

    摘要： The present invention relates to an optical information recording medium including a disk-shaped transparent substrate and a recording layer for recording, reproducing or erasing information by irradiation of laser light, the recording layer being formed over the substrate. The recording layer of the present invention includes information tracks including groove tracks and land tracks that are formed alternately in a radial direction of the disk. The information tracks comprise information recording regions and address regions interposed between the information recording regions, the information recording regions and the address regions being arranged along the tracking direction of the laser light. In the information recording regions, every second step in the radial direction of steps for dividing the groove tracks from the land tracks adjacent to the groove tracks is wobbled in the tracking direction, and in a range whose ends are defined by the address regions the every second step is wobbled at a constant frequency. Prepit addresses for providing information on a position on the recording medium are formed on the address regions. Moreover, the present invention provides an optical information recording medium including n recording layers (where n is an integer of at least 2), and in at least the first recording layer to the (n−1)th recording layer from the transparent substrate side, no pair of adjacent address regions in the radial direction of the disk are arranged so as to be aligned on a straight line passing through the center of the disk.

    摘要： A plurality of types of recording pulse control rules for which the recording pulse waveform is determined according to the information signals to be recorded are stored in advance in an optical disk. When recording to the optical disk, information is recorded using a recording pulse where, due to the focused laser beam, the temperature in the recording layer cools more rapidly at a second information recording layer closer to the side where light is incident than at a first information recording layer farther away from the side where light is incident.
