ABSTRACT:
An optical disk drive which does not require a high precision servo mechanism and intensive error correction technique. The recording surface of a recording medium is stationary and is completed as a spherical or semi-spherical plane. An optical head is provided at the center of curvature. A laser beam emitted from the optical head, provided at the center of curvature, is displaced physically or electrically, without rotating the recording surface.
