| titleOfInvention | Optical disc with postponed viewing window |
| abstract | An optical storage medium comprising a data layer suitable to be read by means of a radiation beam in an optical scanning apparatus, and access control means for inhibiting reading of at least part of stored information for a predetermined period of time, thereby leading to a postponed viewing window. Preferably the access control means correspond to an access control layer covering at least part of the data layer, chosen to inhibit access to the data layer. The onset of the predetermined period of time may be determined by exposure of the access control layer to an activating substance. A diffusion barrier layer may control the length of the predetermined period of time. Such optical storage medium is preferably used for distributing content having a fixed release date. |
