By some estimates, pressed CD-ROMs may only last for 10 to 25 years,because the aluminum reflective layer starts to corrode after a while.

well i know that nothing lasts forever, and the industry lied about the 100 year shelf life of retail audio discs, but 10-25 years is just too short! my papy’s blue hawaii vinyl lasted longer than that. can anyone confirm this?

my oldest discs are:
rod stewart gasoline alley 1990
beatles sessions 1990
judds river of time 1989

all my discs were new when i bought them, and they’re still doing and playing great these days.

IMHO most pressed CDs will last for at least 30 - 40 years. I have several CDs from 1985-1990 and they are still in perfect shape.
However, discs from several manufacturers (PDO UK, Opti.Me.S Italy) may be affected by"CD bronzing" and could have became unreadable after only a few years.

hi, thanks for letting me know about this! well lucky for me none of my cds were purchased in those regions.

by the time they are no good, there might not be any players around to play them.
