Pro mene znale anglictiny aby se tim nemuseli celym louskat:

It is true that phthalocyanine dye is less sensitive to ordinary light 
-- incoherent, random light such as sunshine, ultra violet, 
incandescent, and fluorescent light normally found in the real world 
outside of CD recorders. That means that prolonged exposure to bright 
light -- particularly bright UV light -- will render cyanine media 
unreadable sooner than phthalocyanine. Phthalocyanine will probably last 
longer and preserve information better under these adverse, but 
extremely unlikely conditions.

Some CD players and CD-ROM drives will read discs recorded on cyanine 
media more readily and reliably than they will read discs recorded on 
phthalocyanine media. This compatibility is tied in with a 
little-discussed concept known as write strategy.

Kazdy at si prebere po svem :)
