    • In a disk camera, when additional information and moving picture information are managed as one file and recorded on an optical disk, useless area is minimized, thereby allowing effective use of recording capacity. A recording controlling part records continuously with respect to a logical block of the optical disk, at least one of input video and audio information in a packet format of a fixed length that is different from a data size of the logical block, and creates a data file for recording with respect to the logical block, additional information with respect to the video or audio information in the packet format of the fixed length. In this one data file, a fixed data size portion of the additional information is arranged in an area ahead of an area in which the video and audio information are arranged, and a variable data size portion of the additional information is arranged in an area behind the area in which the video and audio information are arranged.
    • 当在光盘上记录附加信息和动态图像信息,同时使用盘摄像机将信息作为一个文件进行管理时,通过最小化无用区域来有效地利用记录容量。 记录控制部分生成用于以至少一个输入的视频信息或输入的音频信息以固定长度的分组模式在逻辑块中记录的数据文件。 这与光盘的逻辑块的数据大小不同,并且以固定长度的分组模式记录添加到逻辑块中的视频或音频信息的附加信息。 在这样的数据文件中,附加信息的固定数据大小部分位于记录有视频和音频信息的区域的前面,并且可变数据大小部分位于该区域的后面。
