Is it possible to burn a cd-r disc (say a Red book compliant cd) using consumer cdrw drives that has errors on the bit-patterns?
If so, what software is needed?
In more detail:
AFAIK, C1/C2 errors are bit-pattern errors flagged by the CIRC-error correction levels 1 and 2 as such (C1 and C2 decoders respectively). In practice they come 99.99999999% (I can't guess how many nines) from the interplay between the media and the reader, due to tracking/reflectivity/etc issues.
However, there can also be bit level errors on a theoretical perfect disc that will get flagged as various C1 and C2 errors respectively. All you need is enough consecutive bits wrong on the disc (actually encoded wrong, not just read wrong off the disc).
I know such specially pressed manufactured test discs with erroneus bit-patterns (i.e. actual data not matching with code words) are available, but they are very expensive.
Even if you don't agree with that academic point of how C1/C2 are defined, please assume for the sake of discussion that there can be bit-errors even on a theoretically pristine disc that is read perfectly in every reader. These are bits that are (purposefully) encoded wrong to produce a mis-match in the CIRC circuitry of the reading drive. An example of this in real life are Cactus Data Shield protected audio discs, although they contain other type of read related errors as well (i.e. they are not theoretically perfect in that regard).
No amount of re-reading will change these bits to correct (unless of course the reading becomes erroneus in statistical terms and changes these incorrect bits back to correct again, but let's rule that out for now).
So, what I'm asking (to reiterate) is:
Can I write a cd containing a bit pattern (simplified example, I have not calculated exact Reed-Solomon codes nor is this an accurate example of data I want to write):
CD should contain correct data and correct checksum:
00 00 00 00 00 with the checksum 0000
But I want to write:
11 11 11 11 11 with the checksum 0000
So that the checksum will not match the actual content bit data.
Actually, to be more precise, can I just write a copy of a CD where a number of consecutive bits have been reversed from the original cd data, without the having the burn process change the Reed-Solomon codes to reflect these changes? I want the actual data content and codewords to mismatch.
Is this possible in raw mode or some other form of writing with consumer cdrw drives?
I hope I have made myself more clear this time. If not, please ask for a clarification. I'm no expert here, so I may have explained myself poorly.
