    摘要： An apparatus records main information and sub information onto an information recording medium, which has a main recording area and a sub recording area. The apparatus is provided with an receiving device that receives the main information input from the external source; an accumulating device that accumulates the main information received by the receiving device; a recording device that records the main information and the sub information to the main recording area and the sub recording area, respectively; and a controller that determines whether or not an amount of the main information accumulated in the accumulating device is smaller than a predetermined amount, and that controls the recording device. In the apparatus, the recording device records the sub information to the sub recording area under a control of the controller if the controller determines that the amount of the main information accumulated in the accumulating device is smaller than the predetermined amount, and the recording device records the main information to the main recording area under a control of the controller if the controller determines that the amount of the main information accumulated in the accumulating device is not smaller than the predetermined amount.

    摘要： A clock signal generating system of the present invention is provided for recording information on a disc. The disc has a plurality of recording tracks wobbled by a wobble signal having a predetermined frequency and a plurality of prepits disposed at positions having a predetermined phase relation with respect to a phase of the wobble signal. A clock signal is generated based on the wobble signal. A prepit signal is produced from the prepit. The phase of the wobble signal is compared with a phase of the prepit signal, thereby generating a phase adjusting signal. The phase of the clock signal is adjusted based on the phase adjusting signal. A recording clock signal for recording the information is produced by an adjusted clock signal.

    摘要： An optical recording medium for accurately deriving the address information or the disc rotation control information despite narrow track pitch and for recording signals to a high density, and a method and apparatus for recording and/or reproducing such optical recording medium. The optical recording medium has a wobbled groove and pits formed at a pre-set interval in an area between turns of the wobbled groove. The recording/reproducing method includes controlling rotation of the optical recording medium by a wobbled signal from the groove and detecting the position on the optical recording medium of a recording signal by pit signals detected from the pits. The recording/reproducing apparatus includes a detection device for detecting the wobbled signal from the groove and a detection device for detecting pit signals from the pits. The rotation of the optical recording medium is controlled by the wobbled signals detected from the groove and the position on the optical recording medium of the recording signal is detected by the pit signal detected from the pits.

    摘要： An apparatus (C) manufactures an information record medium (DK), which has a track (G, L), on which information is optically recorded. The apparatus is provided with: a track forming device (40, 43, 50) for forming the track; and a transition portion forming device (40, 43, 50) for forming a transition portion (MG) for transiting an irradiation position (SP) of a light beam (LG, LL), which is used for illegally copying the information on the formed track, from an irradiation track (G2), which is irradiated by the light beam, to an adjacent track (G1), which is adjacent to the irradiation track and on which the information is recorded before the information is recorded on the irradiation track, such that the formed transition portion is continuous with the formed track.
