Abstract
A slider for an optical head for signal recording and/or reproduction on or from a recording medium which, even if reduced in size, assures optimum signal recording and/or reproduction on or from a recording medium, and which may be produced readily. The slider for the optical head includes a slider member for floating and running over a recording medium during recording and/or reproduction of information signals for the recording medium, an optical lens bonded to the slider member and a magnetic field generating unit provided on a surface of the slider member carrying the optical lens facing the recording medium. The slider member is formed with a terminal groove opened in a its surface facing the recording medium and in its lateral surface, with an electrically conductive material being charged in the terminal groove. The electrically conductive material charged forms a terminal electrically connected to the magnetic field generating unit. One end of the terminal faces to outside of the slider member from a lateral surface of the slider member.
