    摘要: An optical storage medium (20) comprises a first data layer (21), for example a Blu-ray (BD) data layer. In addition, the optical storage medium (20) comprises a second data layer (23), for example a DVD data layer. The second data layer (23) is bonded to a substrate (25) using a third layer (27). The third layer (27) comprises an adhesive layer combined with a reactive layer. A reactive agent contained in the reactive layer acts to provide a limited lifetime to the data contained in the second layer (23). The second data layer (23) (i.e. having a limited lifetime) contains access data for controlling access to at least some of the data contained on the first data layer (21). In this way, access to a BD layer can be controlled by a separate DVD layer having a limited lifetime.

    摘要: A write-once optical recording medium and a method and apparatus for recording management information on the recording medium, are provided. The recording medium includes at least one recording layer and SRR information on the recording layer. The SRR information pertains to at least one SRR and includes a header, an SRR entry list, and a terminator. The SRR entry list includes a plurality of SRR entries, each of the SRR entries pertaining to an SRR and including at least one status area for storing therein session start information.
