<p>On a data storage medium (104), sector headers (202) include data that are used to control behavior of a drive (102) reading the data storage medium. For example, the header data may specify, for each sector, whether a reading drive is permitted to send unencrypted sector data to a requesting device (100), whether authentication of a requestor is required, or whether the sector data can be transferred outside the drive. <IMAGE></p> |
