    Abstract: A recording apparatus for an optical recording medium (1) having a pregroove and address data includes a recording head apparatus (4-7) and a controller (11). The recording head apparatus (4-7) has an optical head device (4) and records data on the optical recording medium (1) along the pregroove. The optical head device (4) radiates a light beam having an intensity which is enough to record the data on the optical recording medium (1). The optical head device (4) includes a detector. The controller (11) controls the recording head apparatus and receives an output signal supplied from the detector. The optical head device (4) is controlled to move a recording start point from the previous recording start point by a predetermined value when the controller (11) detects the occurrence of a recording error according to the output signal from the detector and restarted to record the data from the moved recording start point on the optical recording medium (1).

    Abstract: PROBLEM TO BE SOLVED: To make it possible to record data on an optical disk by efficiently utilizing the recording capacity of the optical disk.
    SOLUTION: In this method for recording data on an optical disk, data are recorded on the optical disk by making a cluster consisting of a plurality of continuous sectors a unit while deciding the recording positions of the sectors with address information with respect to the optical disk on which the address information expressing a sector as the minimum unit is continuously recorded in a data rate lower than that of the data to be recorded.

    Abstract: PROBLEM TO BE SOLVED: To improve convenience in a recording and reproducing device for realizing the synchronous reproduction of a sound track and a sub-data file. SOLUTION: When a search operation using AUX data as a reference is executed, access is performed to the address of a program corresponding to the display start time of a picture file which is being reproduced at present, or access is performed to the address of a program corresponding to the display start time of a picture file which is reproduction-temporally one ahead the picture file which is being reproduced at present, or access is performed to the address of a program corresponding to the display start time of a picture file which is reproduction-temporally one behind the picture file which is being reproduced at present according to the search operation. Thus, the reproduction of the program can be started.

    Abstract: PROBLEM TO BE SOLVED: To make data recording performable while securing the continuity of recording data, even in the occurrence of an abnormality in a recording operation such as track-jumping. SOLUTION: This optical disk device is equipped with an optical head 3 for emitting a laser beam to an optical disk 2 rotatably driven by a spindle motor 1, a circuit 6 for performing the tracking control of this optical head 3, an abnormality detecting means 30 which is provided with a circuit 32 for detecting the generation of track-jumping based on a tracking error signal and with a circuit 33 for detecting discontinuity of recording data, a control circuit 7 for lowering the output of the optical head 3 when an abnormality of recording operation is detected by the means 30, and a memory 14 in which data writing is performed even in the detection of an abnormality of recording operation, and at the time of detection of an abnormality in recording operation by the detecting means 30 during the data recording, the device lowers the output of the optical head 3, returning to the starting end of the cluster where an abnormality is detected in the recording data, resuming the recording operation, and recording the data stored in the memory 14.

    Abstract: PROBLEM TO BE SOLVED: To improve the operability when air-checked contents are reproduced. SOLUTION: Among various types of information data which are character information data which are read out at the time of reproduction, the character information data corresponding to title information data are identified as specific types. As the title information data are transmitted when the broadcast of a music is started and recorded simultaneously, the address of the sound data of the starting part of a certain music can be estimated from an address in which the title information data are stored. Therefore, if program segmentation points TM1-TM4 are set in accordance with the address of the title information data concerning the recorded broadcast sound, one track as the recorded broadcast sound is edited and divided into a plurality of tracks (TK1-TK5) at the starting point of the music. With this constitution, the starting point of the music can be accessed at the time of reproduction afterwards.
