A recording pulse controlling method according to the present invention is a recording pulse controlling method for adjusting recording pulses for recording information on a writable optical disc, which includes a mark length adjustment step and a mark position adjustment step. The mark length adjustment step is a step for adjusting a recording mark length adjustment parameter, and the recording mark length adjustment parameter is adjusted to have a value for forming a recording mark having a length closest to a predetermined recording mark length. The mark position adjustment step is a step for adjusting a recording mark position adjustment parameter after the mark length adjustment step, and the recording mark position adjustment parameter is adjusted to have a value for forming a recording mark at a position closest to a predetermined recording mark position.

摘要： 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.
