The CD-ROM errors are:

but the error was recovered by read retry. Number of read retries to perform

ECC (Layered Error Correction Code) is not used.

specified number of read retries were attempted.
3) Recovered L-ECC Error:
Uncorrectable CIRC Error was found, but the error was corrected by the L-
ECC during read retries.
4) Uncorrectable L-ECC Error:

retries were attempted.
