ABSTRACT:
An optical information recording apparatus for recording information on an optical information recording medium with multiple recording layers is disclosed. The optical information recording apparatus, performing an OPC operation before performing the recording, includes a reading part reading information on the type of the medium recorded thereon, a storage unit storing information on a recording condition at the time of performing the OPC operation for each recording layer with respect to each medium type, a recording condition obtaining part reading out the recording condition corresponding to the read type when the recording condition is stored in the storage unit, and reading the recording condition recorded in a corresponding one of the recording layers recording their respective recording conditions when the recording condition is not stored in the storage unit, and an OPC performance part performing the OPC operation using the obtained recording condition.
