Split Disc Optical Storage Medium and Device

摘要

Optical data storage medium comprising a first disc ( 11 ) and a second disc ( 12 ) both having an access surface ( 16 ) and a storage layer covered by the access surface, wherein the storage layer is adapted to be accessed by a laser beam via the access surface, characterized in that the first disc and the second disc are adapted to be attached to each other in such a way, that the access surface of the first disc covers the access surface of the second disc. Further a device for reproducing information from or recording information into at least one storage layer of such an optical data storage medium.
