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 9.4GB of information, and the wafers are stacked in layers of 100 or so, giving overall data storage increase of 100x or more.

SVOD will likely be a candidate, along with HVDs, to be the next-generation optical disc standard.^{[citation needed]}
