Ive always wondered why blu-ray players use blue diodes that are expensive compared to red or ir. I can only think of like 2 reasons for this maybe because the shorter nm will focus smaller, or because they have the name blue-ray?
I also think i see a pattern, cd burners use ir, dvd burners use red, blu-ray's use blue/violet. Since they go in order of how much data they hold cd's at the least dvd's next and blu-ray's next, does that also mean its because of the short wavelength.
...lazer.... ;D ;D ;D
