now, in DVD they learned their lesson
data-dvd and video-dvd both use a 'file structure' and so aren't strictly streaming disk formats. they are a lot more reliable than cd format is.
some people will save their ripped .wav files in a 'data cd' (iso9660 format) so that they can KNOW if their data is all there or if they had bit errors from the media. but regular audio players don't recognize ISO formated non-redbook audio cd's.
|Btw, why are we still using this error prone audio format? It is kind of anti-HiFi... or maybe not, since that's why they can sell those expensive cd players.
cd is a has-been. 'they' learned their lesson with dvd and it does have another reliability layer that cd-da did not have.
hey, even in the mp3 format they added a checksum so that you can know if your file is corrupt or not. most ignore that feature but its still there.
you used to have to pay $400 for a plextor scsi cdrom to be able to get quality cd-da rips. but now even a $20 dvdrom drive can do just about as well. this pretty much killed all commonplace use of cd 'transports' (for most of us; I do realize there are those that prefer old methods for various reasons...)
