ABSTRACT
Japanese research organisation NTT has produced a prototype read-only 1Gbyte holographic memory. Data is stored in a stack of storage medium called 'info-MICA.' To read, an electromagnetic servo introduces a laser into the appropriate layer and the constructed hologram image is captured by an image detector. Image processing extracts the data. Data in the form of holograms are pressed into each layer during manufacture.
