Patent ID: 7990819

Claim:
An optical head apparatus comprising: a first optical system including a first light source and a first objective lens for focusing a first light beam emitted from the first light source upon a first optical disc; a second optical system including a second light source emitting a second light beam having a wavelength longer than the first light source and a second objective lens for focusing the second light beam emitted from the second light source upon a second optical disc; a first reflecting surface for deflecting the first light beam and guiding the first light beam toward the first objective lens in the first optical system; and a second reflecting surface for deflecting the second light beam and guiding the second light beam toward the second objective lens in the second optical system; wherein the second optical disc has an information recording density smaller than the first optical disc, the first objective lens and the second objective lens are arranged along a tangential direction to a track on an optical disc, and the second objective lens is disposed on a line substantially passing a center of the optical disc, and the first objective lens is disposed at a position out of the line.
