Abstract
Abstract A recording and reproducing system employing both a multichannel magnetic tape (32) as a high capacity storage medium and a magnetic disk (46) as a random access storage medium in order to combine their advantages while compensating for the shortcomings of each other. A switching circuit (16) operates under the direction of a programmable system controller (26) for simultaneously or selectively delivering a plurality of channels of input information, such as digital audio signals, to a tape drive (12) and a disk drive (14), and for simultaneously or selectively delivering the information retrieved from the tape and that retrieved from the disk to system output terminals (20-1, 20-2, 20-n). Information transfer is also possible between the tape drive (12) and the disk drive (14) through the switching circuit (16), so that the system permits a variety of editing operations of the recorded information. <IMAGE>
