Abstract: A recording/reproducing device and a recording/reproducing method for recording a program reproduced from a first recording medium onto a second recording medium having at least two recording regions and onto a third recording medium in synchronism. The recording region may be changed over on the second recording medium. In this case, after the change-over of the recording region of the second recording medium has been completed, the head of the program reproduced from the first recording medium when the change-over of the recording region occurred is recorded onto the second recording medium and into the third recording medium, and the program that was incompletely recorded into the third recording medium is erased after the recording. Therefore, the program that had been recorded during the change-over of the recording region of the second recording medium is completely recorded, and the program is further completely recorded into the third recording medium.

Abstract: A recording/reproducing device and a recording/reproducing method for dubbing a program reproduced from a first recording medium into a second recording medium having at least two recording regions and into a third recording medium in synchronism. The recording region may be changed over on the second recording medium. In this case, after the change-over of the recording region of said second recording medium has been completed, from the head of the program reproduced from the first recording medium when the change-over of the recording region occurred is dubbed into the second recording medium and into the third recording medium, and the program that is incompletely recorded into the third recording medium is erased after the dubbing. Therefore, the program that had been recorded during the change-over of the recording region of the second recording medium is completely recorded, and the program is further completely recorded into the third recording medium.
