PURPOSE:To obtain a slider suitable for a thin film recording medium, by mixing small quantities of one, at least, of CaO, MgO, and Y2O3 and ZrO2 into materials consisting of 20-60wt% TiO2 and the balance Al2O3. CONSTITUTION:0.5-5pts.wt. one, at least, of CaO, MgO, and Y2O3 and 0.5- 10pts.wt. ZrO2 having >=99% purity and <=2mum average particle size desirably are added to 100pts.wt. materials consisting of 20-60wt% TiO2 and the balance Al2O3, and a head slider is constituted with alumina magnetic materials obtained by sintering these components after mixing and molding them or by sintering them by the hot press method or the hot hyrostatic pressure press method. Thus, the head slider which is superior in lubrication and is fitted well to a recording medium is produced. Specially this head slider is suitable for a thin film recording medium. |
