Abstract
A record and playback apparatus for use with magnetic tape cassettes and the like can be switched between the normal two track cassette format for either record or playback or single track format for either record or playback. The apparatus provides optimum record and bias signals to the record head gaps being used regardless of whether two record head gaps are used for standard format or a single record head gap is used for single track format. The apparatus also preferably includes motor speed switching and regulating circuitry so that the apparatus can be satisfactorily operated at normal cassette speed or at a reduced speed, preferably one quarter that of normal speed. Switching of play and record equalization as well as record bias is also preferably included with the speed switching.
