PROBLEM TO BE SOLVED: To miniaturize a shape with simple constitution by adapting an optical pickup and optical disk device, particularly the optical disk device for accessing a magneto-optical disk. SOLUTION: A member 47D having double refractiveness and a member 47B consisting of a glass material are combined and are arranged on a semiconductor substrate 45. A laser beam L1 is emitted via these members 47D, 47B, and the return light L2 from the magneto-optical disk is received. The optical pickup, which may be miniaturized in the shape and the optical disk device using this optical pickup, may be obtd. with the simple constitution by combining the member having the double refraction property and the member consisting of the glass material, arranging the members on the semiconductor substrate, emitting the laser beam via these members and receiving the return light from the magneto-optical disk in the manner described. |
