Stacked Volumetric Optical Disc
The Stacked Volumetric Optical Disc (or SVOD) is an optical disc https://en.wikipedia.org/wiki/Optical_disc format developed by Hitachi Maxell https://en.wikipedia.org/wiki/Hitachi_Maxell, which uses an array of wafer-thin optical discs to allow data storage. Each "layer" (a thin polycarbonate https://en.wikipedia.org/wiki/Polycarbonate disc) holds around 9.4 GB[1] https://en.wikipedia.org/wiki/Stacked_Volumetric_Optical_Disc#cite_note-1 of information, and the wafers are stacked in layers of 20, 25, 100, or more, giving a substantially larger overall data capacity; for example, 100× cartridges could hold 940 GB using the system as announced.
