ABSTRACT:
A method of recording information on a tape-like record carrier by means of a device provided with a rotary head disc on which a write head with controllable height is mounted for actively following the tracks. During recording tracking signals are written with the aid of a separate fixed head, which preferably also constitutes the erase head, and the write head follows the tracking signal recorded by the fixed head during the recording of information.
