Abstract
A head and a method to manufacture a head are disclosed. A slider is provided and has a mounting face that is opposite but substantially parallel to its air bearing surface. According to an example embodiment, a first plurality of layers may be deposited on the mounting face, including a tin layer, a first underlayer that comprises platinum, and an interface layer disposed between the first underlayer and the tin layer. The interface layer may comprise Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, or W. A submount with an attached laser diode may include a gold layer and be positioned adjacent to the first plurality of layers. The tin layer may then be melted so that the gold layer is dissolved therein, upon solidification attaching the submount to the mounting face by a solder layer that preferably comprises at least 45% gold by weight dissolved in tin.
