ABSTRACT:
The disclosure relates to a device for recording information in a servo-track (2) of a record carrier (1) of a rewritable type. Pieces of information, for example, in the form of pieces of music (tracks) are recorded in the servo-track (2) in accordance with first recording instructions. According to these first recording instructions information patterns representing a piece of information are allowed to be rewritten with information patterns for a new piece of information. At a later instant the information in the servo-track is rearranged. During that operation information recorded in accordance with the first recording instructions is read out and rewritten in accordance with second recording instructions. These second recording instructions prescribe that the pieces of information intended to be read out be recorded in the servo-track as a continuous series of information patterns and that the information patterns representing a piece of information be uninterrupted.
