US 2006/0136955 A1 · Optical pickup actuator having aberration correcting mechanism and method of assembling the same

Abstract

An optical pickup actuator and a method of assembling the same is provided. The method of assembling the optical pickup actuator comprises the steps of providing a blade having at least one objective lens mounting area and an aberration correcting mechanism mounting area, arranging an objective lens in the objective lens mounting area, positioning an aberration correcting mechanism in the aberration correcting mechanism mounting area such that the central point of the aberration correcting mechanism coincides with the central point of the objective lens, tuning the aberration correction mechanism, and adhering the aberration correcting mechanism using an adhesive.

Dependent claims

An optical pickup actuator comprising:

at least one objective lens which focuses a laser beam to an optical disc;
an aberration correcting mechanism which corrects a wave front of the laser beam incident into the at least one objective lens;
a voltage applying substrate arranged to perpendicularly contact and electrically connect with the aberration correcting mechanism to apply voltage;
and
a blade which supports the objective lens, the aberration correcting mechanism and the voltage applying substrate, wherein the blade moves in tracking and focus directions.
