Abstract
A slider for magnetic data recording in a thermally assisted recording system. The slider has a slider body and a magnetic recording head formed on a trailing edge of the slider body. A first terminal is formed on a trailing edge surface of the recording head, and a second terminal is formed on a backside surface both the magnetic recording head and the slider body so as to extend across both the magnetic recording head and the slider body. An electrically conductive lead formed within the magnetic recording head connects the first lead with the second lead.
Claims21
A magnetic recording slider, comprising:
- a slider body having an air bearing surface a backside surface opposite the air bearing surface and a trailing edge surface;
- a head formed on the trailing edge surface, the head having a trailing edge surface and a backside surface;
- an electrically conductive first terminal formed on the trailing edge surface of the head;
- an electrically conductive second terminal formed on the backside surface of the head and the backside surface of the slider body;
- and
- an electrical lead formed within the head and connecting the electrically conductive first terminal with the electrically conductive second terminal.
A method for manufacturing a magnetic recording slider, comprising.
- forming a slider row having a backside surface and having a recording head formed on a trailing edge surface of the slider row, the recording head having a trailing edge surface and a backside surface, and having an electrically conductive first terminal formed on the trailing edge surface of the recording head, and having an electrical lead line connected with the first terminal and extending through the recording head to the back side surface of the recording head;
- forming a photoresist mask on the backside surfaces of the slider body and recording head, the photoresist being formed with an opening configured to define a second terminal pattern that extends over a portion of the slider body and a portion of the recording head;
- and
- depositing an electrically conductive material to form a second terminal on the backside surfaces of the slider body and recording head.
