What?? If you're referring to the recording process, then yes, absolutely, both achieve the same result provided they're done accurately enough that the words can be read back again without error. And the reverse is true as well - whether you read a handwritten article or a printed one, the information is exactly, identically the same. Does this web page, for example, look different whether you downloaded it via wired Ethernet or over wi-fi? Can you tell by looking at this post whether I'm using a wired or a wireless connection right now? The transport medium is completely different in both cases, so what's the effect on the data? pfarrell;214074 Wrote: > It depends. An audio CD player reads the music per the RedBook spec.

So the error correcting codes specified for CD-DA vs CD-ROM are different. So what? The biggest problem was actually the inability to do a random seek to a particular sector of an audio disc because there's no sophisticated index like there is on a CD-ROM - but that's like saying that a book whose pages aren't numbered is different from a book whose pages are. (Maybe the book with page numbering is also printed in a slightly different, clearer font too - but you get my point). > I believe, that if the spec had been written just five years later, it > would have been very different, using more of a digital approach from > the start.
