    • Embodiments of the invention reduce damage to a disk recording medium when a slider flying above the disk recording medium inside a magnetic disk drive comes into contact with the disk recording medium due to slider vibration. In one embodiment, a magnetic head slider includes a front pad, a rear pad, and carbon protective films. The front pad includes a step bearing surface disposed on the side of a leading end and leading side rail surfaces formed on the step bearing surface. The rear pad includes a rear step bearing surface disposed across a deep groove surface from the front pad and a trailing side rail surface formed on the rear step bearing surface. The carbon protective films are formed on regions including vertices of slider corner portions, respectively. The leading side rail surfaces and the trailing side rail surface are formed substantially on the same level. The carbon protective films are harder than a slider base material and have a small coefficient of friction. The films have a film thickness of about 10 nm or more.
    • 当在磁盘驱动器内的盘记录介质上方的滑块与滑块振动与盘记录介质接触时,本发明的实施例减少对盘记录介质的损坏。 在一个实施例中,磁头滑块包括前垫,后垫和碳保护膜。 前垫包括设置在前端侧的台阶承载面和形成在台阶承载面上的前侧侧轨面。 后垫包括一个后台阶支承表面,该表面设置在远离前垫的深槽表面和形成在后台阶承载表面上的后侧轨面上。 碳保护膜分别形成在包括滑块拐角部分的顶点的区域上。 前导侧轨面和后侧轨道表面基本上形成在同一水平面上。 碳保护膜比滑块基材硬,摩擦系数小。 膜的膜厚度为约10nm以上。
