Abstract
A method for producing a slider for an optical head includes a slider member adapted for floating and running over a recording medium during recording and/or reproduction of information signals for the recording medium. An optical lens is bonded to the slider member and a magnetic field generator provided on a surface of the slider member carrying the optical lens facing the recording medium. A first step is forming a groove presenting a bottom surface inclined in the depth-wise direction by ejecting a polishing agent dispersed in a compressed gas on a substrate. A second step is charging an electrically conductive material, which proves a terminal electrically connected to the magnetic field generator in the inside of the groove formed in the substrate. A third step is cutting the substrate in the vicinity of an end of the groove to form a plurality of individual slider members.
