Abstract

비디오 카세트 레코더의 기록재생용 자기헤드에 있어서, 코팅막의 밀착력 및 강도가 저하하는 문제를 해소하기 위해, 헤드에 다이아몬드 성분과 그래파이트 성분의 비가 2.5∼3.5인 DLC(Diamond Like Carbon) 막을 코팅한다.In the magnetic head for recording and reproducing of a video cassette recorder, in order to solve the problem of low adhesion and strength of the coating film, the head is coated with a DLC (Diamond Like Carbon) film having a ratio of diamond component and graphite component of 2.5 to 3.5.

이와 같은 자기헤드를 이용하는 것에 의해, 자기헤드의 내마모성 및 내스크래치성이 우수하여, 자기헤드의 수명을 확보할 수가 있다.By using such a magnetic head, it is excellent in the abrasion resistance and scratch resistance of a magnetic head, and can ensure the lifetime of a magnetic head.
