Abstract
An information signal recording and/or reproducing apparatus is arranged to be capable of quickly and accurately discriminating between recording and unrecording of an information signal on a tape-shaped recording medium by detecting all of signals sequentially reproduced from the tape-shaped recording medium by a plurality of rotary heads which trace the tape-shaped recording medium. The real end part of any existing record can be accurately detected by transporting the tape-shaped recording medium in a direction reverse to the direction taken in recording, according to the result of the discrimination; and by initializing a counter which counts pulses generated according to the transport of the recording medium, in response to the recording of the information signal being detected in process of transporting the tape-shaped recording medium in the reverse direction.
