Abstract
A light source unit for thermally-assisted magnetic head includes a support member and a light source attached on the support member via a solder, and the light source unit further includes a positioning structure formed between the support member and the light source for positioning the light source and the solder. The light source unit can maintain stable height control of the light source, prevent solder over flow and prevent the light source from shifting and moving during the bonding process.
