Why does the same drive have errors in audio but none in data?, Split from "Digitalizing my CD collection, EAC/dBpa/fb2k?"

I'm not trying to hijack the thread but I have a question about the optical disc drives. Your operating system and software was likely loaded from an optical drive. Bit errors in .EXE files can render the file useless but this rarely happens. Why does that same drive have errors in audio but none in data?

The reason that audio CDs hold so much more data then do data CDs is that there is a lot more redundancy built into data disks. Thus its much less likely that data will be corrupted on a data disk.

That said, baring significant damage, its pretty rare to see any corruption in audio CDs either.
