Tokyo, Japan, Oct 14, 2004 (JCNN via COMTEX) -- Victor Company of Japan (JVC) (TSE:6792) announced October 13 that it has developed the world's first single lens with a numeric aperture of 0.95.

The ultra-small lens has a focal length of 0.75mm, and is 1.2mm in thickness and 2.1mm in diameter, about 25% smaller in lens surface area than the smallest Blu-ray disc system lens (NA of 0.85) the company has already developed.

In principle, the new lens will enable reading of more than 40GB of data recorded on a 120mm-diameter single-layer disc.

JVC will apply the lens to optical pickups for use with Blue-ray/DVD/CD discs as well as mobile devices
