The discs listed above were tested during 2003. Archived results of older discs can be seen here.

Disclaimer

These recordable discs have been tested as a free service for members of the IDDA as a guide only, and the IDDA and any organizations that have assisted with the tests accept no responsibility for the accuracy of these evaluations and the use of the data.

Whilst care has been taken with these evaluations, they are to be considered a rough guide only. Many factors can affect the results, such as the testing equipment, the recorder used, recording speed, ambient conditions, and even wear and condition of the stamper used to make the disc. Disc brands and qualities will also vary between states and countries, and from batch to batch.

The IDDA has at this stage tested only for BLER (Block Error Rates), as we believe that for recordable discs this is the most useful test of the recordability and playability of the discs. If the discs are good, then we have enough information. If the discs are bad, then there is a variety of other tests that are required to determine why the disc is bad, such as tests for eccentricity, reflectivity, jitter, to name a few. These other tests are not covered here.

The manufacturer stated is based on results obtained using "CDR Identifier" software, and it is acknowledged that at best, this is an indicator of the manufacturer of the stamper used to create the discs, not necessarily the actual manufacturer. Members may download a copy of "CDR Identifier" (212 kb). You may also view the "ReadMe" text file that came with the program.

The IDDA invites members, users and manufacturers to contribute and submit their own tests, and to send the results of any tests by any testing equipment along with two clean, unused discs in standard jewel cases for verification to

International Disc Duplicating Association,
Shop 8.06,
100 Miller Street
