Abstract

Jitter of 9.5% with conventional equalizer and 6.1% with limit equalizer have been achieved on a 23.3GB blue-violet laser write-once optical disc with a recording laeyr formed by spin coating with a dye-based solution. Data transfer speed is 36Mbit/s. The disc is composed of a polycarbonate substrate, a reflective layer, a dye-coated recording layer, a bonding layer, and a polycarbonate protective sheet. Cavities formed in the marks during recording result in large changes in refractive index for signal amplitude. Recording and playback was successful even at 2x drive speeds with data transfer of 72Mbit/s.
