Abstract
A playback unit (3) reproduces contents which are recorded on a video cassette tape (2), and a recording unit (6) records the contents on another video cassette tape (7) and, simultaneously, an erasing unit (5) erases the contents from the video cassette tape (2).
Thereby, the copy-inhibited contents recorded on the video cassette tape (2) can be transferred to the other video cassette tape (7) without copying the contents.
