An optical medium has auxiliary information (116) and control data (118) encoded in wobble. The control data specifies action that a drive is permitted or required to take with the auxiliary information. For example, the control data may be used to specify whether a drive reading the medium is permitted to output a region of the auxiliary information (204, 206). Alternatively, the control data may be used to specify whether a writing drive is permitted to copy a portion of the auxiliary information to a writeable area on the medium (304, 306). |
