아날로그 정보신호를 디지탈 펄스 변조를 하여 이루어진 디지탈 신호를 소정기간마다 끊어 얻어진 데이터워드와 이 데이터워드중 다른 트랙에 기록되는 데이터워드를 포함한 복수의 데이터워드로부터 생성되는 착오데이터워드를 복원(復元)하기 위한 착오정정워드와 동일프레임 신호의 데이터 착오를 검사하는 착오검사워드와 1프레임 신호중 데이터워드의 시작을 나타내는 동기워드가 시계열적으로 합성되어 기록되는 트랙을 복수개수가 동시에 테이프형 자기기록매체에 기록되는 장치에 있어서 이 테이프형 자기기록매체의 너비 방향위의 연부에 가장 가까운 위치에 형성되는 1개 또는 2개의 트랙에는 이 동기워드, 착오정정워드 및 착오검사워드로 이루어진 쓸데없이 긴 워드만을 기록하고, 다른 트랙에 동기워드, 착오검사워드 및 데이터워드로 이루어진 신호를 각각 기록하는 것을 특징으로 하는 디지탈 신호의 자기 기록 방식.Restoring a mistaken dataword generated from a plurality of datawords including a dataword obtained by breaking a digital signal generated by digital pulse modulation of an analog information signal every predetermined period and a dataword recorded in another track among the datawords. A plurality of tracks in which a mistaken correction word for checking data error of the same frame signal and a synchronization word indicating the start of a data word in one frame signal are synthesized in time series are recorded on a tape-type magnetic recording medium simultaneously. In one device or two tracks formed at the position closest to the edge of the tape-shaped magnetic recording medium in the width direction, only the uselessly long words consisting of this sync word, error correction word and error check word are recorded. , Sync words, error check words and data words A magnetic recording method of a digital signal, characterized in that each recorded signal. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
