비데오신호와, 디지탈데이타가 트럭단위로 혼재하여 기록 재생되는 플로피디스크의 드라이브에 있어서, 어떤 트럭과, 이 트럭에 인접하는 트럭과의 신호의 조합을 표시하는 테이블을 가지고, 소정의 트럭에 신호를 액세스하는 경우, 상기 테이블이 참조되고, 상기 소정의 트럭이 상기 비데오신호의 트럭인 때 및 상기 소정의 트럭이 상기 비데오신호의 트럭인 때 및 상기 소정의 트럭이 상기한 디지탈데이타의 트럭이고, 또한, 인접하는 트럭의 적어도 한쪽이 상기 비데오 신호의 트럭인 때, 클로우즈 된 루우프의 서보제어에 의해 헤드의 위치를 결정하고, 상기 소정의 트럭 및 인접하는 트럭의 모두가 상기 디지탈데이타의 트럭일 때, 오픈루프의 제어에 의해 상기 헤드의 위치를 결정하고, 상기 헤드의 위치를 결정한 후, 상기 소정의 트럭에 신호를 액세스하도록 한 플로피디스크 드라이브.In a drive of a floppy disk in which video signals and digital data are mixed and recorded on a truck basis, a table displaying a combination of signals between a truck and a truck adjacent to the truck is provided to a predetermined truck. When accessing, the table is referenced, when the predetermined truck is the truck of the video signal, and when the predetermined truck is the truck of the video signal, and the predetermined truck is the truck of the digital data, and When at least one of the adjacent trucks is the truck of the video signal, the head position is determined by servo control of the closed loop, and when all of the predetermined truck and the adjacent trucks are the trucks of the digital data, The position of the head is determined by the control of an open loop, and after determining the position of the head, a signal is applied to the predetermined truck. A floppy disk drive to Scotland. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
