Abstract
A thermally assisted magnetic recording head slider includes a light source unit having a light emitting element emitting laser light and a submount holding the light emitting element, and slider including a thin-film laminated part having a main magnetic pole layer, a near-field light generating element and an optical waveguide. A combination of the light emitting element and near-field light generating element is composed of a first pattern or second pattern. The light source unit is mounted on a light source placing surface so that a substrate surface of the light emitting element is orthogonal to a laminated surface of the thin-film laminated part. A plurality of electrode pads are formed on the outer end surface of the slider. The light source unit has a first element electrode and second element electrode. A first connecting wiring part and second connecting wiring part, which connected the first element electrode and second element electrode with a first electrode pad and second electrode pad, are formed on a light source placing surface.
