ABSTRACT:
An optical device integrated head having high light utilizing efficiency by decreasing the propagation loss caused from an optical source to a recording medium, conducting by mounting according to compact active alignment method for efficiently guiding a light generated from a laser device to the top end of a head, in which a light source device mounted on a submount has a mirror portion having an inclinated surface to at least a portion of one edge thereof for reflecting an output light from the optical source device at the inclinated surface, a structural member including a lens structure for further allowing a light to pass through the submount, and an optical waveguide disposed passing through a slider for mounting the submount, and the optical source and the slider are positioned by using active alignment of light in a chip-on carrier structure having the optical source device mounted on the submount.
