My uncle had a big laserdisc collection unfortunately it succumed to laser rot. The discs were breaking down over time. He bought them in the 70's or 80's and by the 2000s they were deteriorating.
I see bots still posting this comment on every platform when optical media comes up. Disc rot is extremely rare and only happens with discs which had manufacturing defects. I have HUNDREDS of Laserdiscs and HUNDREDS more CDs. The only ones which rotted is Alien, which had a known manufacturing defect.
