Abstract
A method of editing a plurality of information signals recorded on a recording medium is provided. According to this method, information signals which are required for editing and which are included among the signals already recorded on the recording medium are indicated. Then such indicated signals are reproduced and recorded on the same recording medium in sequence and a recording control device is caused to recognize the area on the recording medium where the indicated signals are not newly recorded, as an empty area free of recorded signals, to thereby make the best use of the recording area of the recording medium.
