Abstract

We have developed an optical pickup head for blu-ray disc. We have adopted a liquid crystal panel to compensate thickness difference of cover layer. By disposing DVD/CD compatible objective inside the BD objective in disc radial direction, we could realize a backward compatibility. Furthermore we have inserted a polarization diffractive optical element to reduce the influence from the other layer in BD dual layer.
