Abstract
A video tape recorder with the function of repetitive playback mainly used for learning purposes detects whether a recordable tape or a playback only tape is used as a master tape when driving independently two video tapes with tape ends to be used as a slave tape and a master tape, respectively. When it is detected that a recordable tape is used, at first the two tapes are simultaneously driven in a recording condition by manipulating a record button and then a desired range of the slave tape is repeatedly rewound and replayed by pressing and releasing a playback button for a required time period. When it is detected that a playback only tape is used, on the other hand, only the slave tape is driven in a recording condition by a similar manipulation, and while the slave tape is repeatedly rewound and replayed, the master tape playback operation is suspended.
