摘要： Provided is a light source unit that is to be joined to a slider to form a thermally-assisted magnetic recording head. The light source unit comprises: a unit substrate having a source-installation surface; a light source provided in the source-installation surface and emitting thermal-assist light; and a photodetector bonded to a rear joining surface of the unit substrate in such a manner that a rear light-emission center of the light source is covered with a light-receiving surface of the photodetector. The photodetector can be sufficiently close to the light source; thus, constant feedback adjustment with high efficiency for the light output of the light source can be performed. This adjustment enables light output from the light source to be controlled in response to changes in light output due to surroundings and to changes with time to stabilize the intensity of light with which a magnetic recording medium is irradiated.

摘要： A probe assembly used to lap a bar, the bar being provided with elements that are to be formed into sliders, is provided. The probe assembly comprises an elastically deflectable probe, and a stopper for applying bending deformation to the probe so as to cause first bending deflection at a leading end of the probe and for maintaining the first bending deflection of the leading end while preventing a bending deformation at the leading end from becoming smaller than the first bending deflection. The leading end of the probe is adapted to be subjected to second bending deflection that is larger than the first bending deflection in a same direction as a direction of the first bending deflection and thereby to abut against an electrode pad to establish electrical connection between the probe and the electrode pad, the electrode pad being provided on a surface of the bar other than a surface to be lapped.
