ABSTRACT:
A parallel and continuous playback circuit for an audio cassette deck of the double-deck type (A-deck and B-deck) includes signal detectors for detecting the tape signal of the playback head of each deck during playback, pulse generators for generating arbitrary pulses when an unrecorded blank portion is detected by the signal detectors, a deck selector for selecting the playback mode of the A-deck or the B-deck in parallel, i.e. alternately, upon detection of an unrecorded portion on the tape being played back in the other deck and for pausing playback of the tape in the deck in which the unrecorded portion is detected, and an error prevention circuit for preventing erroneous operation of the deck selector after selection of the other deck and upon encountering and unrecorded portion such as as the start of the tape in the selected deck. The playback circuit offers the advantage of playing back of the tape cassette in the other deck when an unrecorded portion is detected on the tape cassette in the deck currently being played back, thus alternating playback between the A-deck and B-deck in distinction to double cassette decks of the serial play or relay play type which play back the entire cassette in one deck before changing playback to the cassette in the other deck, and so on. The parallel and continuous playback circuit thus alleviates the tedium of listening to unrecorded blank portions of the cassettes by switching playback to the other deck of the double-deck.
