  • Optical recording medium and data recording device
    Patent number: 7764300
    Abstract: In an optical disk manufacturable by a conventional recording medium manufacturing method and that is capable of performing recording with an information recording apparatus used to perform recording on conventional recording mediums, and a data recording apparatus for recording contents data, an optical disk has a structure in which a first substrate and a second substrate are bonded together, the first substrate is provided with a recording layer in which contents data is recorded, and the second substrate is provided with a visual information recording layer in which information enabling visual recognition of, for example, the contents of contents data or a title of the contents data is recorded as visual information.
    Type: Grant

  • Data processing apparatus, data processing method, information storing medium, and computer program
    Patent number: 6999090
    Abstract: An information storing medium storing coded data of a content in segment units stores data including information of a horizontal video size, a vertical video size, a video depth, a maximum video data size in data segments, and a maximum audio data size in data segments as header information corresponding to the content. The stored data also includes information of the first frame number within a data segment, the number of frames within the data segment, and the address of each delimiter relative to the start of the data as segment information. A content reproducing apparatus can perform FIFO setting, data reading, and reproduction processing applying these pieces of information in a cache.
