Inorganic material for high speed write-once FVD disc

Abstract A new inorganic recording media is introduced for write-once type forward versatile disc. Experimental result shows that the recording characteristics of jitter are obtained to be 5.5% at 18.5 mW, 6.1% at 25 mW and 7.2% at 32 mW, respectively, for 4×, 8× and 12× recording speed with track pitch of 0.74 μm. And the recording characteristics of jitter are obtained to be 7.27% at 19 mW and 7.55% at 25.5 mW, respectively, for 4× and 8× recording speed with track pitch of 0.64 μm.
