Abstract
In the recording of information signals the signal elements of which are to have a prescribed length, a read/write head (WRT) is used in which the write gap (W1) is at a distance from the read gap (R) corresponding to the prescribed length. When a signal edge occurs at the read gap (R), an evaluation circuit (FIG. 4) controls the write gap (W1) in such a way that the latter records the next signal edge. For recording by the NRZ process, a further write gap (W2) can be provided between the write gap (W1) and the read gap R, which is controlled like the first and makes possible the recording of binary signals.
