ABSTRACT:
An information recording-playback apparatus is made up of a circuit for recording first information, which is video data or data for the evaluation of a recording medium such as a magnetic tape, on the first track formed by helical scanning of rotary heads, a circuit for recording second information such as a control signal or time code or third information on a second or third track formed by one or more fixed heads in the longitudinal direction of the tape, and switching device for selecting the operational mode in which the first information and the second or third information are recorded or the operational mode in which only the second or third information is recorded. The arrangement enables pre-formatting of only the second or third information without recording the tape evaluation information.
