ABSTRACT:
A recording and/or reproducing system for a 4-head type recording and/or reproducing apparatus, comprises a circuit for recording a head discriminating information signal of each of the four heads during the recording, a circuit for reproducing this head discriminating information signal during the reproduction, and a circuit for controlling the rotational phase of the heads so that the recorded tracks on the magnetic tape are reproduced by the same heads which recorded these tracks at the time of the recording. In addition, a magnetic tape having such a discriminating signal recorded thereon, can be played in a conventional 2-head recording and/or reproducing apparatus.
