Abstract

See full text

A method for setting protection states of optical disc media is provided. The method includes setting a first protection state for the optical disc media. A second protection state which is configured to replace the first protection state is then set for the optical disc media. After the second protection state is set, a third protection state which is configured to replace the second protection state is set for the optical disc media. The first protection state is configured to replace the third protection state. Thus, the method also includes reverting from the third protection state back to the first protection state. The reverting is configured to skip a transition through the second protection state. Furthermore, a user may cycle through the first protection state, the second protection state and the third protection state as the user deems necessary.
