<p>An optical medium has auxiliary information (116) and control data (118) encodedin wobble. The control data specifies action that a drive is permitted or requiredto take with the auxiliary information. For example, the control data may be usedto specify whether a drive reading the medium is permitted to output a region ofthe auxiliary information (204, 206). Alternatively, the control data may beused to specify whether a writing drive is permitted to copy a portion of the auxiliaryinformation to a writeable area on the medium (304, 306).</p> |
