A method to protect content within protected data areas on a target optical record carrier against unauthorized reading and/or copying with a computer, comprises the steps of-determining whether a target optical record carrier or a non-target optical record carrier is inserted into a drive of the computer, and-in case a target optical record carrier is inserted into the drive of the computer-modifying read requests to the protected data areas so that no data is read or the read data is useless, and/or-modifying write commands in respect to the data within the protected data areas to a recordable record carrier or other storage so that the written data is useless.
