Abstract

In the case of a recorder with a rotating head drum (3), the signal has to be transmitted by means of a transmitting element between a stationary part and the head drum (3). The object is to provide optimum transmission both for recording and for playback. This is achieved by the signal transmission taking place via different transmitting elements, for example slip rings and rotation transmitters, assigned to the head drum (3), during recording and during playback. In particular for a recorder for recording a digital video or audio signal.
