"The CD-ROM format is so incredibly unreliable that all of the layers of error corrections require 2.33 GB to encode 650 MB of usable data."

Oh, I forgot, the author of this article is on Mastodon since this is blowing up: @byuu

@Jo It does, that is what @byuu 's post it about, he proposes a better archival format.

@Canageek @polychrome wow indeed! I worked for a duplication & fulfilment firm back in the day, and actually wrote and maintained CD duplication software used in-house in the 90s. I had to grok most of the stuff in that article to do so. The first Philips CD recorder was a massive empty box apart from the power transformer and the drive itself. It only wrote at 1x, and the discs were expensive, so development was a challenge!

@polychrome @WearsManyHats Error checking. They have to encode things more then once due to how bad the format is

@Canageek @WearsManyHats oh on the media, I thought you were talking about the hardware for some reason :blobpats:

@polychrome @Canageek because CDs were sold to the public as being indestructible and perfect. That didn’t turn out to be the case. For recordable and rewritable discs, even less so.

@WearsManyHats @Canageek actually I remember them being sold as 'extremely delicate and prone to die if but a single particle of dust lands on the reflective surface of perfection' - which is why I was really confused by seeing people just pile them up on top of each other.

The only stable part of this I remember being billed was that the data was supposed to be much safer than on magnetic media (which turned out to be false, too :blobnervous: )

@polychrome @Canageek CD capacity topped out at 800MB as fabrication tech got better, though older drives might struggle to read all of the disc.

@WearsManyHats @Canageek yah that was interesting to finally learn how they pulled it off :blobmelt:
