Encyclopedia > Stacked Volumetric Optical Disk

The Stacked Volumetric Optical Disk (or SVOD) is an optical disk format developed by Hitachi/Maxell, which uses an array of wafer-thin optical disks to allow data storage of around 1TB. Each "wafer" (a thin polycarbonate disk) 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 disk standard. In computing, sound reproduction, and video, an optical disc is flat, circular, usually polycarbonate disc whereon data is stored. ...
