Abstract
An optical storage medium () comprises a first data layer (), for example a Blu-ray (BD) data layer. In addition, the optical storage medium () comprises a second data layer (), for example a DVD data layer. The second data layer () is bonded to a substrate () using a third layer (). The third layer () 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 (). The second data layer () (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 (). In this way, access to a BD layer can be controlled by a separate DVD layer having a limited lifetime.
