Abstract
To reduce the position deviation of the beam spot on the detector when there was a significant variation in temperature, we developed the jisso structure of an ultra-slim optical pickup. We clarified opticle parts that have a strong effect on the position deviation on the detector and modified the combination of the ways to fix these optical parts to the optical pickup case. The results that we calculated show that the position deviation on the detector of the improved optical pickup is reduced to below 3μm in ambient temperatures between 0 and 65℃.
