Abstract :
This paper evaluates MultiLevel (ML) margin-testing results as applied to a blue-laser recording-base with 0.85 NA lens and media with 0.1 mm cover for an 8-level trellis-coded modulation system that encodes 2.5 user-bits per data-cell. The ML system tested was originally developed on a CD-R/RW base to achieve 2 GB. Margin testing results compare favorably to binary system performance on this same tester and produced a 36% increase in capacity above a 25 GB base.
