Abstract: An optical data storage system comprises a multiple data surface medium and optical head. The medium comprises a plurality of substrates separated by a light transmissive medium. Data surfaces are located on the substrate surfaces which lie adjacent a light transmissive medium. The data surfaces are substantially light transmissive. The optical head includes an aberration compensator to allow the head to focus onto the different data surfaces and a filter to screen out unwanted reflected light.

Abstract: Described is an optical data storage system which comprises a multiple data surface medium (12) and optical head. The medium comprises a plurality of substrates (50,56,62,68) separated by a light transmissive medium. Data surfaces are located on the substrate surfaces which lie adjacent to a light transmissive medium. The data surfaces are substantially light transmissive. Some of the data recorded in the first data surface represent the number of separate data surfaces contained in the medium.
