Abstract
본 발명은 자기헤드용 비자성 세라믹 기판재료를 금속자성박막의 열팽창 계수에 근접되고, 자기 테이프의 접촉주행시 마모가 적고, 가공성이 양호한 재질로 하여 자성 박막층의 박리 및 균열 억제등에 따라 사용 수명을 증대시키는데 적합한 비자성 세라믹 기판재료에 관한 것으로, CaO 10-35mole%, Tio210-40mole%, NiO 10-60mole%, CoO 10-50mole%로 조성됨을 특징으로 하는 자기헤드용 비자성 세라믹 기판재료.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
첨부된 도면은 테이프 주행시간에 따른 자기헤드 마모량의 변화를 나타낸 그래프.
