Researchers at the University of Shanghai for Science and Technology have developed an optical disc with a capacity of over a petabit of data, equivalent to well...
I’m not familiar with it either, but I’d say that using RAID on a single disc is silly… There’s a good reason it’s not a common practice on single HDDs.
A scratch on the disc usually means many scratches on the disc.
With a rate 1/2 you can’t expect to correct more than 5.5% of errors.
I am unfamiliar with the math used to calculate that value.
Would it not work like a parity RAID where each sector would have parity bits in a different location on the disc?
