Abstract
A time code signal is reproduced from a running tape of an audio tape recorder and is used to search a desired tape stop position. There are provided time code comparing means (13) for comparing same or difference between data of a reproduced time code indicative of the present tape position and a cue point position at which the tape should be stopped (1), mode control means (14) for producing a mode specifying signal on the basis of the compared result of the time code comparing means (13), and timer control means (15) for producing a head drive signal to permit a reproducing head of the audio tape recorder (1) to contact with or leave the tape on the basis of the outputs from the time code comparing means (13) and the mode control means (14). While the tape is being transported, the time code signal recorded thereon is reproduced by the reproducing head, the time code data indicative of the present tape position and the cue point position at which the tape should be stopped are compared with each other, the tape running mode is controlled on the basis of the compared result and the reproducing head is allowed to contact with or leave the tape in accordance with the compared data …
