Since this is an open matter, no full text was included.

3 is a block diagram of a digital signal reproducing and recording apparatus according to the present invention capable of reproducing a compact disc and a digital audio tape, respectively, and recording a compact disc sound on a digital audio tape.

Claims (2)

A servo circuit for generating a control signal for reproducing sound recorded on the disk, a disk reproducing mechanism device for reading out a digital signal recorded on the disc by operating by the above disk servo circuit, and by the above mechanism device Disc reproducing means having a first digital signal processor for processing the read digital signal, and a digital reproducing sound recorded on a digital audio tape to generate a control signal for recording a predetermined digital signal on the tape. An audio tape servo circuit, a digital audio tape deck for operating the tape servo circuit, for reading and recording digital signals recorded on the digital audio tape, and for converting an externally input analog signal into a digital signal. Analog-to-digital converter and the above first digital signal processing at the time of reproduction The digital signal output from the digital signal or the digital signal of the digital audio tape read by the digital audio tape deck is processed and output to the outside, and during recording, the digital signal is processed by processing the digital signal output from the first digital signal processor. A disc / tape recording means having a second digital signal processor for recording on a tape or processing a signal input after being converted into a digital signal by the analog / digital converter and recording on the digital audio tape; And when the disc sound is recorded on the digital audio tape, provide a digital signal output from the first digital signal processor to the second digital signal processor, and reproduce only a tape for recording a digital signal of an external device on the digital audio tape. In case of the first digital Digital signal switching means for cutting off a digital signal of the call processor and providing an external digital signal to the second digital signal processor, a signal for selectively operating the disc reproducing means and the disc / tape recording means; A key input means having a key for generating a signal for recording a disc sound on a digital audio tape, a key exclusive means for operating said disc, and a disc / tape recording means operated by a key signal generated by said key input means. And a control means for controlling the digital signal switching means, a digital filter for inputting and filtering the digital signal output from the second digital signal processor, and a digital signal filtered by the digital filter. Digital / Analog Converter for Converting to Analog Signal and Filtering the Analog Signal Display means for visually displaying the operating states of the disc reproducing means and the disc / tape recording means by inputting an analog output means having a low pass filter for outputting to the outside and another control signal outputted from the control means Digital signal playback and recording device, characterized in that consisting of. The digital input device according to claim 1, wherein the key input means includes a key for selectively operating the disc and the digital audio tape, and a synchronous recording key for synchronizing the disc groove with the digital audio tape. Signal playback and recording device ※ Note: The disclosure is based on the initial application.
