Abstract

본 발명은 비지성 세라믹 기판을 금속자성막의 열팽창계수에 근접하는 재료로 하여 금속자성박막의 박리, 쪼개짐등의 발생을 억제하고 테이프 주행시 헤드의 습동 내마모성을 향상시켜 자기헤드 사용 수명을 연상하는데 적합한 기판재료와 그 제조방법에 관한 것으로, MnO 115~45mol%, NiO 25~65mol%, TiO210~30mol%로 하거나 여기서 Al2O3, Y2O3, ZrO2, CaO, SiO2중에서 1종 또는 2종 이상을 첨가하여서 된 기판 재료로 이루어진 기술에 관한 것이다.According to the present invention, the non-ceramic ceramic substrate is made of a material close to the thermal expansion coefficient of the magnetic metal film, which suppresses the peeling and cracking of the magnetic metal film, and improves the sliding wear resistance of the head during tape driving, which is suitable for associating the service life of the magnetic head. A substrate material and a method for manufacturing the same, MnO 115 ~ 45mol%, NiO 25 ~ 65mol%, TiO 2 10 ~ 30mol% or where Al 1 O 3 , Y 2 O 3 , ZrO 2 , CaO, SiO 2 It relates to a technique made of a substrate material obtained by adding a species or two or more kinds.
