摘要 An optical disc apparatus records information onto plural disc shaped mediums of different standards or reproduces information from the plural disc shaped mediums. The optical disc apparatus includes an optical pickup equipped with a spherical aberration correcting unit using a movable lens, and a disc insertion unit for inserting and ejecting the disc shaped mediums. The spherical aberration correcting unit starts the movement of the movable lens to an initial position while the disc insertion unit inserts or ejects the disc shaped medium. As such, the present invention discloses the optical disc apparatus with a reduced disc recognition time for improving user convenience and a driving method thereof.
