Optical disk drive having magnets for generating attractive or repulsive forces

摘要

Magnets for seeking provided for the base and magnets for focusing provided for a carriage are so arranged that they are shifted perpendicularly relative to each other. With this arrangement, since the attractive force or the repulsive force, which includes a perpendicular element, is generated between the magnets for seeking and the magnets for focusing, the urging force to the carriage against guide rails can be adjusted.
