Abstract

자기헤드의 기록후의 자화(磁化)상태를 확실히 소자(消磁)한다.The magnetization state after recording of the magnetic head is reliably elemental.

자기헤드에 의한 자기디스크에의 기록종료시 t₂에 콘트롤러로부터 보내오는 라이트게이트 A가 닫히고, 후에 소정시간 라이트데이터 B가 공급되는 동시에, 자기헤드에 주어지는 기록전류 C를 감쇠시키는 기능을 구비한다.At the end of recording on the magnetic disk by the magnetic head, the write gate A sent from the controller is closed at t2, and later, the write data B is supplied for a predetermined time and attenuates the recording current C given to the magnetic head.
