Abstract:
The present invention relates to a holographic storage medium, and more specifically to a holographic storage medium with an improved servo architecture for precise positioning of a laser beam in radial, axial and tangential direction. According to the invention, a holographic storage medium includes a holographic layer for storing holograms and a servo layer with a track structure for positioning a light beam for reading and/or recording of a hologram relative to the holographic recording medium, wherein the track structure includes a pack of two or more tracks.
