ABSTRACT:
An automatic switching device for a cassette tape recorder is provided which includes a detecting member disposed within the tape recorder for cooperation with at least one detection opening provided in a tape cassette so as to indicate the variety of a magnetic tape internally housed therein, thereby establishing an optimum bias and/or an optimum tape speed for the tape recorder, a compensation circuit compensates for low frequency signals recorded on the tape when the detecting member determines that such compensation is desirable.
