Abstract
Abstract Apparatus for reproducing a recording selected from a plurality of recordings on magnetic tape includes a plurality of tape decks each for reproducing a respective magnetic tape in the form of an endless loop bearing a plurality of recordings on separate tracks, selector means by which a user can indicate a recording selected for reproduction, means responsive to the selector means to select for operation the tape deck having the magnetic tape bearing the selected recording, and means responsive to the selector means to select for reproduction the selected recording on the magnetic tape of the tape deck selected for operation. A search unit is operatively connected to the selector unit and is adapted to perform a scanning operation to determine the next selected recording to be reproduced. The search unit controls a deck selecting unit operatively connected with a motor of each tape deck and a track selecting unit operatively connected to a reproducing head of each tape deck. The two selecting units respond to the search unit to select for operation the motor of the tape deck which has the magnetic tape bearing the selected recording to be reproduced and to set the reproducing head of the tape deck selected for operation so as to achieve reproduction of the track corresponding to the selected recording. An indicating unit monitors the operation of the deck and track selecting units and is operatively connected to amplifier means to energize such amplifier means to amplify the output of the reproducing heads when the required track has been selected.
