Abstract:
1. A method for producing a slider for an optical head, including a slider member adapted for floating and running over a recording medium during recording and/or reproduction of information signals for said recording medium, an optical lens bonded to said slider member and a magnetic field generating means provided on a surface of said slider member carrying said optical lens facing said recording medium; said method comprising: a first step of forming a groove presenting a bottom surface inclined in the depth-wise direction by ejecting a jet comprised of a polishing agent dispersed in a compressed gas on a substrate which proves said slider member; a second step of charging an electrically conductive material, which proves a terminal electrically connected to said magnetic field generating means, in the inside of said groove formed in said substrate wherein a plurality of metal materials at least including gold are charged as the metal materials are layered sequentially; and a third step of cutting said substrate in the vicinity of an end of said groove to form a plurality of individual slider members wherein, said substrate is cut in the vicinity of the end of said groove into individual slider members; and wherein the sectional surface of said slider member as cut is ground until the gold portion is exposed.
