Title: Optical disk reproducing device
Inventor: ONO MASUMI
IPC: G11B7/09
Filed: 2000-11-10
Abstract: PROBLEM TO BE SOLVED: To stably perform the tracking control of a FAD type SR disk by a comparatively simple optical system. SOLUTION: For reproducing the optical disk (FAD type SR disk), a side spot SP1 is formed on the information signal surface of the optical disk in addition to a main spot SP0 for signal reproduction. The spot SP0 is made to have such a light intensity allowing the reproduction of super high resolution in such a manner that the temperature of the partial area PX of a phase transition material layer in the spot SP0 is made to the fusing point or higher and the reflectivity is lowered by shifting this spot to the fused state from the crystallized state. The spot SP1 is kept to the crystallized state without making the temperature of the phase transition material layer in the spot SP1 equal to the fusing point or higher, so as to have the light intensity not lowering the reflectivity. The tracking control is made by the push-pull method based on the light reflected from the spot SP1.  The number of side spots is reduced by one as compared with the 3-beam method, and the optical system is thereby made to be simple. The phase transition material layer in the spot SP1 is kept in the crystallized state and not adversely affected due to the left/right asymmetry of the fused state.
