Abstract

2.1. In the case of recorders, it is known to record in addition to the useful signal a tracking control signal, by which the position of the head (K1) in relation to the track (S) is controlled during playback. The aim is that the tracking control signal can be recorded during the entire length of the track (S) without disturbing the useful signal. 2.2. A second head (K2), having a gap length (w2) which is great in comparison with the gap length (w1) of the head (K1) for the useful signal is provided for the tracking control signal. 2.3. In particular for a recorder with matrix-like recording according to German Offenlegungsschrift 3,509,584. <IMAGE>
