  • Objective lens drive apparatus where interaction of drive magnets and drive coils drive a holding member that holds the objective lens and optical pickup and optical disk apparatus including the same
    Patent number: 8255936
    Abstract: An objective lens drive apparatus configured to drive an objective lens that focuses a laser beam on an optical disk is disclosed, the apparatus including a holding member that holds the objective lens; at least one pair of drive magnets arranged to face each other at opposite sides of the holding member with respect a tangential direction that is parallel to a tangential line of the optical disk, the drive magnets having protruding end portions that protrude from each side of the holding member with respect to a tracking direction that is parallel to a radial direction of the optical disk; and plural drive coils configured to drive the holding member through interaction with the drive magnets, at least one of the drive coils being arranged on each side of the drive magnets with respect to the tangential direction.
