Patent ID: 7936644

Claim:
An optical pickup device capable of optically accessing an optical disk, the optical disk being any one of a plurality of different types of optical disks including a first optical disk and a second optical disk, the optical pickup device comprising: a first objective lens for converging red laser light onto a recording surface of the first optical disk to perform reproduction or recording for the first optical disk, the first objective lens having a working distance of W 1 with respect to the first optical disk; a second objective lens for converging blue laser light onto a recording surface of the second optical disk to perform reproduction or recording for the second optical disk, the second objective lens having a working distance of W 2 with respect to the second optical disk, where the relationship W 1 >W 2 is satisfied; a lens holder for holding the first and second objective lenses so that a second proximal point of the second objective lens with respect to the optical disk is closer to the optical disk, by a distance x, than is a first proximal point of the first objective lens with respect to the optical disk; and a protective member which is provided on the lens holder and more protruding toward the optical disk, by a distance d, than is the second proximal point of the second objective lens, wherein, the first objective lens, the second objective lens and the protective member are arranged on the lens holder so as to satisfy the relationship 0<x ≦{W 1 -(d+h)}, where h is a height of a protrusion formed in an inner peripheral region of a light incident surface of the first optical disk.
