How it works

After the recording phase begins, the micro-controller inside the CD-R/RW drive always monitors the status of the buffer. When the drive judges that a Buffer Under run Error is about to happen, it suspends recording at the appropriate location of the EFM (Eight-to-Fourteen Modulation) pattern. While the drive stays in suspend mode, it continues trying to receive data from the host PC to fill-up its data buffer and subsequently prepares itself to restart recording by accessing the end of the previously recorded area (EFM pattern).

To continue recording at the appropriate place, the drive compares the recorded data with the data in buffer for synchronizing adjacent frames. In simpler terms, it restarts recording as soon as it exactly locates the last recorded point. Because the micro-controller in the drive stores the suspended recording address, it controls the status of both the buffer and the servo-mechanism so that the drive restarts recording at exactly the previously suspended recording point.

I've had a little phone conversation with SANYO last week, and they expect that through the year 2000, a considerable large number of drive manufacturers will adopt this technology, and even incorporate it in their next generation products, especially for the 12x+ recording units. Lacie, another high quality CDR- (W) maker, already announced their support in their upcoming products.

The big question is product availability. Currently, this technology is and will be shipping at first with OEM based products. It will begin showing up in retail stores around the end of Q1, starting of Q2. The first available OEM drive will be the SANYO CRD-BP2. Currently SANYO doesn't plan to sell these drives to end users nor retail stores. But as soon as CDR- (W) companies migrate to the BURN-Proof technology we may see a large variety on sale. Around Q2 2000, Sanyo expects to see this technology enabled on IDE based drives.

The merit for users by BURN-Proof function.

 

  • Users can do another work during recording the data because the recording application also doesn't have Buffer under Run Error.
    Example: While decoding MP3 music, you can do make the MP3 disc at the same time.


  • The coaster discs is never made as far as it concerns with Buffer under Run Error.
  • The multi-task will be available by PC.
    Up to now, you can not do any other work by PC while recording the data, but now, you do not have to suspend the work by Burn-Proof function even though you are recording data.

  • The low performance PC will also can be applicable for high-speed recording. The actual recording speed depends on the performance of the data transfer rate of PC.

BURN-Proof technology does not always support all kinds of errors. Some errors on CD-R media may happen under some condition of media's quality, Host PC, Writing Application, Source Device and so on.
