ABSTRACT:
A video signal reproducing apparatus capable of reproducing parallel record tracks formed on a tape which are scanned by a rotary head and wherein track address signals are recorded on respective vertical blanking interval sections of the record tracks which can be read out and displayed even though the tape moves at various speeds comprising a detecting means for detecting when said track address signals are not being read out and including shifting means for shifting the relative position of the rotary heads relative to the tape when the output of the detecting means continues longer than a predetermined time so as to assure that the address signals will be read at varying speeds of the tape.
