Description

자기헤드의 비행높이 제어방법Flying height control method of magnetic head

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 제어방법에 의하여 디스크에 제어용 신호를 기록한 것을 보인 설명도,1 is an explanatory diagram showing that a control signal is recorded on a disc by the control method of the present invention;

제2도는 본 발명의 제어방법에 의한 회로도,2 is a circuit diagram according to the control method of the present invention,

제3도는 본 발명의 제어방법의 신호 흐름도.3 is a signal flow diagram of a control method of the present invention.

Claims (1)

디스크(1)의 0트랙(2)의 외측 및 최종트랙(3)의 내측에 제어트랙(4)(5)을 설정하여 제어신호를 기록하고, 그 기록된 제어신호를 자기헤드로 검출하여 검출된 신호의 크기가 일정기준값과 동일하게 될 때가지 마이크로 프로세서(13)로 자기헤드의 비행높이를 제어하여 그 크기가 기준값과 동일하게 되는 자기헤드의 제어신호의 값을 저장하며, 자기헤드가 트랙을 트래킹할 때 그 저장한 값에 따라 자기헤드의 비행높이를 제어하게 함을 특징으로하는 자기헤드의 비행높이 제어방법.The control tracks 4 and 5 are set outside the zero track 2 of the disc 1 and inside the final track 3 to record the control signals, and the recorded control signals are detected by the magnetic head for detection. The microprocessor 13 controls the flying height of the magnetic head until the magnitude of the signal becomes equal to the predetermined reference value, and stores the value of the control signal of the magnetic head whose magnitude is equal to the reference value. When controlling the flying height of the magnetic head characterized in that to control the flying height of the magnetic head according to the stored value. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
