ABSTRACT:
An optical information recording and reproducing apparatus, and a method thereof which reproduces and records data on a sector on an optical disk. The optical information recording and reproducing apparatus is connected to a host computer. The apparatus includes a normal reproducing component for reproducing the data recorded on the information recording medium under normal reproducing conditions, and a verification, reproducing component for reproducing data recorded on the information recording medium under stricter reproducing conditions than the normal reproducing conditions. 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.
