ABSTRACT:
An apparatus for recording information signals on a record carrier in the form of a tape can be set to an "information-signal-controlled recording" mode. The record carrier is driven by a motor drive arrangement (12) which includes two non-positively cooperating drive elements (15, 16) which are pressed constantly against one another during such recording mode, the motor being started by a motor control circuit (43) upon occurrence of an information signal which is detected by an information signal detector 40. The motor control circuit switches the motor off with a delay following termination of the information signal, and includes a pulse generation device (G) which, if during the recording mode the information signal fails to appear for longer than a time interval (T.sub.2) generates short control signal pulses (M.sub.1) which recur at such time intervals (T.sub.2) and which briefly start the motor, thereby causing the two drive elements (15, 16) to be brought into different positions relative to each other during each of such intervals.
