Abstract: Provided is an optical pickup device and a method of aligning a twin-light source in an optical disc drive. The method operates two light emitting chips in the light source simultaneously to cause two laser beams to be transmitted through a grating element at the same time. Location errors and rotation errors of the two light emitting chips with respect to the grating element may be corrected while monitoring the laser beams transmitted through the grating element.

Abstract: An optical pickup device corresponding to a plurality of media is provided. The optical pickup device includes a light emitting system and a light receiving system including a plurality of light sources and a light transmission system shared by the light emitting system and the light receiving system, configured to irradiate light on a medium, and receive light reflected from the medium.
