Recording and/or reproducing apparatus with tracking servo-mechanism responsive to FM crosstalk components.

摘要

In a recording apparatus frequency modulators (25-28) a provided for modulating carriers having different frequencies with an information signal. The different frequency irriers are sequentially combined by a switch (12) and aplied to a recording head in response to the head being fifted from one track to the next to record each of the carriers a different track, so that there is a difference in frequency between carriers recorded on adjacent tracks. During play- back, the frequency-modulated carriers are sequentially produced and separated by band-pass filters (25-28) into individual carriers, frequency-demodulated respectively by (29-32) and sequentially combined by a switch 3) to form the original information signal. Tracking control (100) is provided to control the lateral position of the ansducer head in response to the carriers which are derived tracks on opposite sides of the track being scanned.
