ABSTRACT:
Cassette changer apparatus for a machine for recording and playing back information on magnetic tape contained in a cassette when located in an operative position. The cassette changer apparatus has a cassette storage magazine and cassette loading apparatus for transporting cassettes between the magazine and the operative position in the machine.
A turntable supports the magazine for rotation about an axis extending through the inverting axis for a cassette in the magazine, so that operating the turntable to rotate the magazine one-half revolution inverts a cassette therein and positions both sets of recording racks on tape in the cassette upon transport to the operative position for use with a mechanism providing playback and/or recording upon a single direction of tape movement. The magazine in preferred embodiment has a plurality of compartments and is translatable to bring any compartment and cassette therein to loading position. Coded elements in a band on the outer surface of the magazine are scanned by optical pick-ups to produce output signals, and control circuits use such output signals to control the magazine movement and locate a selected cassette compartment in loading position.
