ABSTRACT:
A method and apparatus for detecting a specific recording position on a recording medium, wherein a detected cue signal is reproduced at a spontaneous travel speed of the recording medium, the detected cue signal having a frequency corresponding to the frequency of a given cue signal which was recorded at a predetermined recording travel speed of the recording medium at a specific position of the recording medium; and the specific position is determined by counting the frequency of the detected cue signal, taking as a reference a repetitive reel signal having a period which is a function of the rotational frequency of the reel on which the recording medium is wound.
