Abstract

Data including video data and audio data recorded on a tape-like recording medium of a video cassette 12 are read, and position information of at least the video data of the data including the video data and the audio data stored in a cassette-appendant memory as temporary storage means of the video cassette 12 is read. The data including the video data and the audio data read from the tape-like recording medium are edited. The position information is relocated, or the position information is relocated while position information is newly prepared, thereby preparing editing data. Thus, a target portion in the case of up-loading the video data and the audio data from the video cassette 12 to an editing device 14 or the like may be designated in a short period of time.
