Abstract

An optical pickup of an optical recording and reproducing apparatus includes a plurality of object lenses used to record and or reproduce information from / to various types of optical recording media of different recording densities; an actuator for driving the object lenses in a focusing direction and supporting the object lenses to have rolling during movement in the focusing direction; and a pickup base installed to movably go and return in a radial direction of an optical recording medium, and the actuator forming a predetermined angle with respect to the pickup base.

Description

technical field [0001] An aspect of the present invention relates to an optical pickup or an optical pickup for an optical recording and / or reproducing apparatus for recording information to and / or reproducing information from an optical recording medium. [0002] More specifically, an aspect of the present invention relates to an optical pickup of an optical recording and / or reproducing apparatus capable of recording information to a plurality of types of optical recording devices of different densities. media and / or reproduce information from multiple types of optical recording media of different densities, and improve the ability to handle tilted optical recording media. Background technique [0003] The optical pick-up of the optical word recording and / or reproduction device that can record information on the optical disc as the optical recording medium, includes: for moving along the direction of the radius of the optical disc to irradiate light on the recording surface...
