RE: 4K 60FPS video is coming but where are we going to store it? The unexplored potential of optical discs
One big problem with optical media is that they are vulnerable to scratches and the greater the data density, the greater the data damage.
In theory this can be fixed if a format performs its write operations deeper. It can also be bypassed through external protection, like a plastic cover that only opens at a certain spot during reading (3'5 floppy drives worked like that, as well as some optical backup drives).
Personally I've worked with thousands of CDs and DVDs and at most I scratched something like 5. But there are people that are mishandling them and are all scratches. I'm like "dude, did you use the steel brush on this?" ahahaha... These people, "coincidentally", also have a problem with hard disks "hitting" and developing read errors due to the G-shocks.
I used to have problems with homemade dvds. Probably because of the low quality of the media.
But plastic enclosures sounds like a good idea.
