본 발명의 목적은 다이내믹 헤드 로딩시 헤드와 자기 디스크의 충돌을 방지하기 위해 자기 디스크의 회전 속도를 제어하는 방법을 제공함에 있다.It is an object of the present invention to provide a method of controlling the rotational speed of a magnetic disk to prevent collision of the head and the magnetic disk during dynamic head loading.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

다이내믹 헤드 로딩시 헤드와 자기 디스크간의 충돌을 방지하기 위해 헤드 로딩시 자기 디스크의 회전속도를 정상회전속도보다 빠르게 회전시킴으로써 자기 디스크표면에 발생되는 기류의 압력을 크게한다. 자기 디스크표면에 발생된 기류는헤드를 수직상승시키고 헤드가 로드한 후 자기 디스크의 회전속도를 정상회전속도로 감속시킴으로써 헤드와 자기 디스크간의 충돌을 방지할 수 있다.In order to prevent collision between the head and the magnetic disk during dynamic head loading, the pressure of the airflow generated on the surface of the magnetic disk is increased by rotating the rotation speed of the magnetic disk faster than the normal rotation speed during the head loading. The airflow generated on the surface of the magnetic disk can prevent the collision between the head and the magnetic disk by raising the head vertically and decelerating the rotational speed of the magnetic disk to the normal rotational speed after the head is loaded.

4. 발명의 중요한 용도4. Important uses of the invention

자기 디스크 구동장치에 유용히 사용될 수 있다.It can be usefully used for the magnetic disk drive.
