Abstract
A system and method for recording and reproducing information includes a magnetic tape, a magnetic-head unit and an actuator. The magnetic tape has servo tracks containing servo signals. The servo signals have been written with a magnetic head, not shown, having a comparatively large gap length. As a result, the servo signals are recorded deep into the magnetic tape. The magnetic-head unit comprises a read head and a write head to inscribe the track, the read head following a bounding line between adjacent servo tracks and in response to the servo signals read from said servo tracks and by the read head. The system in accordance with the invention is characterized in that it comprises control means which determine the sequence in which the information tracks are written, the read head either following a track or between two respective non-overwritten parts of the magnetic tape, or following a track or between two respective overwritten parts of the magnetic tape.
