A disk drive read head includes a slider. The slider has an air bearing surface, a trailing face, and a mounting face opposite the air bearing surface. The mounting face includes a mounting face recession. An interior surface of the mounting face recession includes an electrically conductive terminal. The read head also includes a magnetic transducer disposed on the trailing face of the slider. The read head also includes a laser device affixed to the electrically conductive terminal by a solder material. The laser device is at least partially recessed into the mounting face recession.

A method for fabricating an air-bearing surface (ABS) in a substrate having a surface is described. The substrate is for a magnetic recording head. The method includes providing a mask on the surface of substrate. The mask has an edge adjacent to a portion of the substrate exposed by the mask. The method also includes forming a taper in the portion of the substrate adjacent to the edge. The taper has an angle from the surface of the substrate of at least thirty degrees and not more than seventy degrees. The method also includes performing a reactive ion etching (RIE) to remove the portion of the substrate to form a cavity in the substrate. The angle of the taper is configured to substantially eliminated redeposition from the RIE on the edge.
