Burn-Proof
In "Disc-at-Once" mode the complete CD is
normally written "in one go". If the computer can not provide the data fast enough,
usually a "Buffer-Underrun" error will occur
and the CD is "rubbish".
Burn-Proof is a technology to prevent "Buffer-Underruns".
When Burn-Proof is used the recording will be continued as soon as data is present
again (simplified).
Question: How does it work, anyway? At "Buffer-Underrun"
you can read, that it is impossible to start over at exactly the same position
where the process has been interrupted?
Answer: At first you have to keep in mind that even Burn-Proof does not succeed
in resuming EXACTLY the same position where the process has been interrupted.
But Burn-Proof is able to "resume" good enough to keep the defective area very
small. Later, the CD-Player will "believe" it is only a small scratch on the
CD. Usually the error correction of the CD-Player will correct such minor errors
itself.
When "Burn-Proof" is used, the data can be basically provided at any speed you
like - the CD-Writer simply stops if not enough data is available.
You will find further information about Burn-Proof on the "Burn-Proof homepage"
( http://www.burn-proof.com/).
Two very interesting quotes from the "Burn-Proof homepage":
Q7: What is the quality of the recorded disc by BURN-Proof ?
A7: Identically BURN-Proof dose not make the overlapped data area and the data-gap
area by suspending and restarting to record. However, the data-gap will happen
by the Auto Power Control Function for the recording laser as follows.
Example: The length of data-gap (unrecorded area) on the disc will be approximately
45 um with 12x speeds.
Q8: Compatibility for each BURN-Proof disc.
A8: The data-gap of around 45 um will be completely corrected by error correction
function.
Therefore, The disc created by BURN-Proof can be handled as the usual recorded
disc.
[NOTICE] To read data, we highly recommend you to use 4X or higher speed CD-ROM
Drive or Audio Equipment made in or after 1995. We haven't made sure the performance
with the drive made before 1995. Some Audio Equipment made 10 or above years
before may have extremely low PLL performance.
Summary: When "Burn-Proof" is used, a small defective area is "created" where
the writer buffer ran empty and a "Buffer-Underrun"
error should normally have occurred. This area should usually be corrected by
CD-Players error correction. However, the manufacturer declares that this won't
work with older CD-Players or CD-ROMs (made before 199.
If you attach importance to "perfect" CDs, you should NOT use Burn-Proof!
ATTENTION:
Due to the defective areas CDs produced with "Burn-Proof" can usually NOT BE
USED FOR MASTERING. I.e. your CD manufacturer will probably send back your "defective"
CD.
SO, DO NOT USE BURN-PROOF TO PRODUCE A MASTER-CD
