2.1.4Error rate

Data blocks to be accessed are evenly distributed on the disk. Errors due to disk defects are not included.

(1) Bit error rate after ECC processing

The error rate after ECC processing must be 10-12or less. An optical disk cartridge whose raw error rate is 10-4or less should be used.

(2) Positioning error rate

The positioning error rate must be 10-6or less. (with retry)
