2.1.4 Error rate

Data blocks to be accessed should be 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 10-12 or less. An optical disk whose
raw error rate is 10-4 or less should be used.
(2) Positioning error rate
The positioning error rate must be 10-6 or less (with retry).
