ABSTRACT:
A rotary type recording and/or reproducing apparatus is provided with a rotary head which is arranged to record and/or reproduce information signals individually on or from a plurality of parallel areas longitudinally extending on a tape-shaped recorded bearing medium by obliquely transversely tracing the plurality of areas; a first detection circuit which is arranged to at least partially detect signals produced from the rotary head; a second detection circuit which is arranged to detect the rotation phase of the rotary head; and an arrangement for outputting a plurality of binary signals which respectively indicate whether the information signals are recorded or not in at least two of the plurality of areas according to the outputs of the first and second detection circuits.
