Paper Abstract

A new master recorder with UV Ar laser ((lambda) equals 351.1) has been developed to study high density optical recording for a future optical video disc system, in combination with high resolution photoresist process. High CNR of 63 dB was demonstrated in 4-times density recording using a read-out optical system with He-Cd laser ((lambda) equals 441.6 nm).
