Abstract

See full text

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.
