Red Book CD Audio still has error correction. Otherwise you'd *really* notice the scratches.

Otherwise, yes, as Dan said, The technology is almost 30 years old, and it's designed much more like a digital phonograph than a computer storage disk. CD-DA isn't even block addressable in the normal sense. The data is written in a continuous spiral from start to finish, with local signposts to help seeking. At the time, I expect there was no expectation of using it for data storage, and no need for the overhead of a conventional filesystem. Even DVD-Video only provides the filesystem structure as a convenience. IIRC it's possible to play a dvd by accessing the ifo files at a fixed offset and using the embedded sector references. -r _______________________________________________ Flac-dev mailing list Flac-dev@xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev
