Hi. Just curious about the workings of the laser in your drive. Does:
- The frequency of the laser change when you go from CD-R(write) to CD-RW(write) to CD-R/RW(read)?
- Does the power of the laser change when you go from CD-R(write) to CD-RW(write) to CD-R/RW(read)?
- Do different drives with different read/write speeds use lasers of different frequency/power, or do they just have faster processors to process the signals from the receive/write parts?
- What is the typical frequency for the laser?
Since one possible colour for the written surface of a CD-R is black, this leads me to suggest that the frequency of the laser must be in the infra-red range. An ultraviolet laser, IMO, would be able to both resolve and write much finer pits, because of its shorter wavelength.
