Abstract
Aiming at obtaining a high CNR (carrier-to-noise ratio) and four times higher recording density than that of the conventional Laser Disc, we have developed a mastering process for a Laser Beam Recorder utilizing an ultraviolet laser. A photoresist claiming high resolution and high CNR has been screened out from the photoresists available on the market. By the improvement of the photoactive component in the photoresist, a CNR of 61.5 dB was obtained in the case of the 4-times higher density.Keywords
