Paper Abstract

The paper describes a novel laser beam mastering system with technologies of direct focus servo, high contrast photoresist material, recording signal compensation. Although the optics consists of conventional 266 nm laser with numerical aperture (NA) 0.9 objective lens, it successfully realizes an over 20 Gbytes capacity Read-Only-Memory (ROM) disc.
