<p>PURPOSE:To execute dubbing in a cassette tape in a short time by temporarily storing all the signals stored in a compact disk, simultaneously reading them from a leading end and an tailing end, and recording them in the A surface and B surface of the cassette tape. CONSTITUTION:A compact disk CD read part 1 reads all the signals stored in the CD at a speed twice as much as a normal read speed and record them in a memory device 2. The memory device 2 simultaneously inputs storage contents to read D/A converters 3 and 4 from the leading end and the tailing end. The outputs of the converters 3 and 4 convert digital signals into analogue signals and they respectively output them to an A surface head 7 and a B surface head 8 through amplifiers 5 and 6. A titled device is constituted in such a way and the A and B surfaces of the cassette tape are simultaneously dubbed, whereby the CD is reproduced in a short time.</p> |
