This small tool was developed to read the ATIP from a CDR media
using a CD recorder - right now thereīs no CDROM reader that can
do this (At least I donīt know of!).
The ATIP tells who has manufactured the disc and what dye type
they used. (The ATIP doesnīt tell the exact dye type - it just
tells if the recording strategy to be used for this media is
a "long strategy type" (e.g. Cyanine) or "short strategy type"
(e.g. Phthalocyanine).
For more information about the ATIP see:
