Also included is a reproduction controlling component for controlling the normal reproducing component and the verifying reproducing component to perform a reproducing operation from the same sector at the same time from the optical disk, and a recovery reporting component for reporting to the host computer when either the normal reproducing component or the verifying, reproducing component can not reproduce the data correctly.
