What is the declared Block Error Rate (BLER) for KODAK CD-R media?
BLER is not just a media property. BLER depends on the speed and condition of the recorder and on the test system used to measure it. For this reason, Kodak does not quote a BLER specification for its media. Kodak bench marked its CD-R media against the major industry brands on multiple occasions. These studies were conducted using the same recording conditions and test equipment for each brand. In these tests, the BLER of Kodak media ranked among the leaders. • Does each CD-R disc have a unique serial number that could be used with programming to prevent duplication? Conventional CD-R discs do not have unique serial numbers recorded on them. Some discs have unique identification numbers printed on them and/or barcoded on them. However, a standard reader or recorder cannot read these numbers and so they are not useful for copy protection.
