Disc life is 25 years before it starts eroding. If you want to see what the process looks like speeded up, look at VHS tapes.
There's no firm, predictable number of years as you're suggesting. I have nearly 40 TG-CD/PCE-CD games that have survived 25 years and not a single one has signs of becoming degraded. The quality of manufacturing and the way the disc has been handled are two factors that you have to consider.
scoobs22, anecdotal evidence means nothing you know? 25 years passing doesn't mean the suddenly break, it means the risk starts to climb from this point onwards.
Yes, I understand that. I also understand that when media manufacturers put a lifespan on their products, they don't really know if it's accurate, and they err on the side of caution to cover themselves. When it comes to how discs are holding up, I guess my collection is all I care about, and my collection is fine.
Worth bumping this thread in the future then. The PCE-CD is a regarded as a high risk with it's discs in particular. Dracula x has a lot of dead discs from disc rot.
I have rarely seen disc rot discussed on any forums etc as far as dead discs go from disc rot let alone of a paticular game such as rondo of blood for the pc engine cd. It is an earlier cd based system so on paper it should have a higher risk than newer cd based systems nothing else.
in general I have not seen many people complain about disc rot and if they have in many cases the discs were abused not the greatest shape found at a flea market garage sale etc etc, it is out there for sure but It's never very clear how the discs were kept not to mention the scale of disc rot on even the older sega based cd games it's pretty rare atm.
I'm very curious where you got this info from as far as the many supposedly dead discs of rondo of blood by disc rot.
and while older cd based games have a higher chance of disc rot these are still game discs they were made allot sturdier than normal discs wich have an even higher chance of disc rot since game discs were products that would have been expected to be used/ replayed allot not to mention by kids.
