I just bought a drive with Lightscribe and I didn't bother to look at the CD's that came with it. It looks like there are about 400 lines per rev. and 80 lines per inch. I was hoping for a 2000 lines per rev. class design. Googling got me a link to Agilent's AEDR-8300 reflective sensor. My first guess is that 80 lines per inch is the maximum resolution for this sensor. Another guess is that they are using geewiz interpolation to get the resolution they need for Lightscribe.
