Abstract
본 발명은 아날로그/디지탈 기록재생장치에 관한 것으로서, 이는 하이파이 헤드와 디지털 비디오 방식의 헤드를 겸용으로 사용하여 로터리 트랜스의 설계 간소화 및 헤드의 삭제에 따른 가격 절감 및 타 제품과의 차별화를 두도록 한 것이다.The present invention relates to an analog / digital recording and reproducing apparatus, which uses a combination of a hi-fi head and a digital video head to simplify the design of the rotary transformer, reduce the cost of eliminating the head, and differentiate it from other products. .
상기와 같은 본 발명은 기록재생장치는 한쌍의 비디오헤드를 갖는 아날로그/디지탈 기록재생장치에서 데크로 로딩된 기록매체의 감지에 따른 마이크로 프로세서의 제1모드선택 제어신호에 의해 주파수변조된 오디오신호 및 채널코딩화된 디지털 신호를 선택적으로 절환하여 디지털 헤드로 공급하는 기록모드 선택수단을 포함하고, 상기 디지털 헤드로부터의 주파수 변조된 오디오신호 또는 채널코딩된 디지털 신호를 상호 동일레벨로 증폭하여 매필드마다 출력하는 제1, 제2 재생증폭수단을 포함하며, 상기 마이크로프로세서의 제2모드선택 제어신호에 의해 상기 재생 오디오신호 또는 디지털 신호를 선택적으로 절환하여 디지털 신호를 디지털 재생 중화수단으로 공급하는 재생모드 선택수단을 포함하고, 상기 재생모드선택수단에서 선택된 신호중 오디오 신호를 소정레벨로 재 증폭하여 오디오 재생등화수단으로 공급하는 오디오재생 증폭수단을 포함하여 이루어짐으로서 달성된다.As described above, the recording and reproducing apparatus includes an audio signal frequency-modulated by a first mode selection control signal of a microprocessor according to the detection of a recording medium loaded into a deck in an analog / digital recording and reproducing apparatus having a pair of video heads. And recording mode selection means for selectively switching a channel coded digital signal to supply the digital head, and amplifying a frequency modulated audio signal or a channel coded digital signal from the digital head to the same level for each field. A reproducing mode including first and second reproducing amplification means for outputting, selectively reproducing the reproducing audio signal or the digital signal by the second mode selection control signal of the microprocessor and supplying the digital signal to the digital reproducing neutralizing means. Among the signals selected by the reproduction mode selecting means, comprising selecting means And an audio reproduction amplifying means for re-amplifying the audio signal to a predetermined level and supplying the audio signal to the audio reproduction equalizing means.
