Stacked Volumetric Optical Disk

The Stacked Volumetric Optical Disc (or SVOD) is an optical disc format developed by Hitachi/Maxell, which uses an array of wafer-thin optical discs to allow data storage.

Each "layer" (a thin polycarbonate disc) holds around 9.4 GB[1] of information, and the wafers are stacked in layers of 100 or so, giving overall data storage increase of 100× or more.

SVOD might likely be a candidate, along with HVDs, to be a next-generation optical disc standard.
