Abstract
A recorded tape, speed-change reproducing system comprises a transport for transporting a tape at a speed which is different from that used for normal reproduction (and recording). The tape carries a video signal which was recorded, by a rotary video head, on parallel video tracks which are disposed obliquely relative to the longitudinal direction of tape travel. An audio signal is recorded by a stationary audio head with an audio track extending longitudinally along the length of the tape. The rotary video heads scan the video tracks on the tape to reproduce the recorded video signal when the tape speed changes. The stationary audio head also scans the audio track on the tape under speed-change situations. The pitch of the reproduced audio signal is corrected in such a manner that the pitch is returned to become substantially equal to the pitch of the reproduced audio signal, as if the tape was travelling at the recording speed.
