You can't always trust that data though. Its unfortunately common for some
CD-R manufacturers to sell off old glass masters to budget CD-R companies,
who (obviously) can't change the data (that would require creating a whole
new glass master). Such companies may then use any one of the numerous dye
compounds when making the actual CD-R, which very well may not reflect the
stored ATIP data from the glass master.
