Patent number: 8218266Abstract: Embodiments of the present invention provide a slider that may suppress contamination from being attached to the flying surface of the slider without influence on reduction of the flying height of the slider. Ions exerting an effect of decreasing surface energy are implanted in the whole surface of a flying surface of a magnetic head slider except for a front rail surface and a center rail surface. According to this, contamination is prevented from being attached to a front step bearing surface, a side step bearing surface, a center step bearing surface and a negative pressure groove where contamination is particularly liable to be attached in the flying surface of the magnetic head slider, so as to suppress destabilization in flying of the slider.Type: GrantFiled: September 7, 2007Date of Patent: July 10, 2012Assignee: HGST Netherlands BVInventors: Yuki Shimizu, Junguo Xu, Jianhua Li, Hidekazu Kohira, Tetsuya Matsusaki, Hidetoshi Anan
