Abstract (en)
[origin: WO2006008669A1] The present invention relates to a device for optical carriers. The device is equipped with a local storage arrangement and a control unit. The control unit controls the storing in the storage arrangement of a set of data that was last written onto the optical carrier. The control unit then triggers the writing of digital rights management data onto the disc and the set of data temporarily stored in the local memory arrangement is written back onto the disc. If the set of data is the Information Control Block associated with the Virtual Allocation Table of the disc, the carrier satisfies to the UDF specification and requirements specific to some DRM related standards such as the Sapphire project.
