What does the term “BLER” mean?
BLER stands for Block Error Rate and is a key measurement relating to CD quality. The lower the error rate the better the reliability to accurately access the disc’s embedded data or music. Errors exist on every disc, even CD-ROMs and audio discs, but it’s the magnitude of these errors that distinguishes good from poor. BLER, therefore, is a measurable way to determine the quality of both CD-R discs and the recorders in which they are used.
