Not Accessible

Your library or personal account may give you access

Abstract

The effect of annular binary phase filters (BPF) on red-light high density optical disk system is investigated. Experimental results show that optical pickups with the BPF of 130 nm etching depth can successfully read out 15G byte disks.
