experienced the same type of problem with Mitsui brand (not readable sectors
at the end of CD), but discs were in paper bags and exposed to home light
(no neon type bulbs) with no direct sunlight.
Not all discs were spoiled, just about 1/5 percentage of all Mitsui CDs I
burned (data mode) for my own purposes.
