Abstract: The movement of the tape is monitored. When the operator recognises during playback of the tape the start position of a tape sequence to be repeated he actuates a start switch upon actuation of which a value corresponding to the monitored tape movement is loaded into a storage or the monitored tape position is assigned to a fixed value. The value is then in any case a read-only value statically stored or assigned. When the operator recognises the end position of the tape sequence he actuates an end switch upon actuation of which a value corresponding to the monitored tape position is loaded into a storage. This value too is then a read-only value statically stored. The two values stored are now compared with the monitored tape movement. Control signals are generated when the stored values match the tape position.
