Abstract: A writable optical information recording medium, an apparatus for reproducing the same, and a method of determining the same are provided. The amplitude of a push-pull signal (PPS) of the writable optical information recording medium is determined to be within an amplitude range of a PPS of a reproduction-only optical information recording medium. Accordingly, it is possible to stably reproduce copy protected content by recognizing a loaded writable optical information recording medium as a medium of a reproduction-only type.

Abstract: An information storage medium includes a drive zone having a plurality of physical clusters or ECC blocks. When new drive data is recorded in the drive zone, the new drive data is recorded in a physical cluster or ECC block next to the physical cluster or ECC block containing the most recently recorded drive data. In the method of recording drive data, the drive data is recorded in a physical cluster or ECC block of the drive zone. When the drive zone is updated with the new drive data, the new drive data is recorded in the physical cluster or ECC block adjacent to physical cluster or ECC block containing the most recently drive data. The drive data recording method is applicable to a new format of information storage medium.
