Abstract

자기 기록/재생장치가 제공되바, 하이파이(HiFi)음성신호 처리용 헤드와 SD, HD음성신호처리용 헤드를 상호 공용할 수 없어 별도로 해당신호 처리용 헤드를 구성하여 처리해야 하는 문제점을 해결하기 위하여 HD헤드의 일부를 HiFi용 헤드로 사용할 수 있도록 하고, VCR에서 VHS규격의 FM음성신호의 기록/재생수단과 HDTV시스템의 디지탈 영상신호의 기록/재생수단을 각각의 모드에 적합하게 작동하도록 절환수단으로 연결구성하면서 자기 헤드를 공용하도록 하며, HD 신호처리용 헤드의 일부를 HiFi 신호처리용 헤드로 사용할 때 딜레이 수단을 사용하여 연속적으로 테이프에 기록하고 재생할 수 있도록 하는 것이다.A magnetic recording / reproducing apparatus is provided. In order to solve the problem that a signal processing head must be configured and processed separately because the head of the HiFi voice signal processing head and the SD and HD voice signal processing head cannot be shared with each other. Switching means for allowing a portion of the HD head to be used as a head for HiFi, and for operating the recording / reproducing means of the VHS standard FM audio signal in the VCR and the recording / reproducing means of the digital video signal of the HDTV system for each mode. The magnetic head is shared while the part of the HD signal processing head is used as the HiFi signal processing head, and the recording means can be continuously recorded and reproduced on the tape by using a delay means.

또한, HD신호처리용 헤드의 일부를 SD신호 처리용 헤드로 사용하여 기록/재생할 수 있도록 하고, HD신호 처리용 헤드의 일부를 SD신호 처리용 헤드로 사용할때 레이트 변환 수단과 지연수단을 사용하여 연속적으로 테이프에 기록재생할 수 있는 HD신호와 SD신호를 겸용으로 처리할 수 있도록 하는 것이다.Also, a part of the HD signal processing head can be used for recording / reproducing by using the SD signal processing head, and a rate converting means and a delay means are used when a part of the HD signal processing head is used as the SD signal processing head. The HD signal and SD signal which can be continuously recorded on the tape can be processed.
