摘要： A reproducing apparatus comprises detecting means 18 and 19 for detecting levels of pilot signals recorded on tracks from reproduced signals reproduced by magnetic heads 1A, 1B, a calculating means 24 for calculating a ratio between levels detected by the detecting means 18 and 19 with respect to the pilot signals recorded on two tracks at both sides of the track traced by the magnetic heads 1A, 1B and a judging means 25 for judging an off-track amount of the magnetic head from the value of the ratio calculated by the calculating means 24, wherein tracking can be effected on the magnetic heads 1A, 1B in response to the off-track amount judged by the judging means 25. In a reproducing apparatus like a VCR (video cassette recorder) in which a magnetic head traces tracks on a tape-like recording medium, tracking can be effected on the magnetic head quickly in a short period of time.
