ABSTRACT:
An apparatus performs recording and/or reproduction of an information signal on or from a tape-shaped record bearing medium arranged to have a main recording area for recording an information signal and a sub-recording area for recording a control signal in a position which is related to the recorded position of the information signal of the main recording area and is not within a non-recording part of a predetermined length in a specific position on the medium. The main recording area and the sub-recording area extend in the longitudinal direction of the medium. The apparatus includes reproducing apparatus for reproducing the control signal from the sub-recording area; determining apparatus for determining whether a change in the output of the reproducing apparatus is caused by a non-recording area of predetermined length; moving apparatus for moving the tape-shaped record bearing medium in the longitudinal direction thereof; and control apparatus for controlling the moving apparatus on the basis of the output of the reproducing apparatus and that of the determining apparatus.
