That command will copy a data disk, but you have separate tracks on this thing.
Ok. And if I want to copy bit by bit ?
You'd have to obtain the glass master used to press the original to get an absolutely exact copy. "bit-by-bit" accuracy of the raw CD is not very easy or even desirable to obtain due to ECC hardware fixing minor errors: for audio, you want a "bit-by-bit" accurate copy of the data after ECC processing, not before.
Better CD-burners let you do something known as DAO+96 ot TAO+96, which lets you override the ECC hardware when reading or writing, and thus copy even the errors from the original, which can be useful for copy-protected data CD's rather than for audio....
