2. Optical storage - Wikipedia

   en.wikipedia.org/wiki/Optical_storage

   An optical disc drive is a device in a computer that can read CD-ROMs or other optical discs, such as DVDs and Blu-ray discs. Optical storage differs from other data storage techniques that make use of other technologies such as magnetism , such as floppy disks and hard disks , or semiconductors , such as flash memory .

3. 3D optical data storage - Wikipedia

   en.wikipedia.org/wiki/3D_optical_data_storage

   Current optical data storage media, such as the CD and DVD store data as a series of reflective marks on an internal surface of a disc. In order to increase storage capacity, it is possible for discs to hold two or even more of these data layers, but their number is severely limited since the addressing laser interacts with every layer that it passes through on the way to and from the ...

   The optical drives in the photos are shown right side up; the disc would sit on top of them. The laser and optical system scans the underside of the disc. With reference to the top photo, just to the right of image center is the disc motor, a metal cylinder, with a gray centering hub and black rubber drive ring on top.

   5D optical data storage (also branded as Superman memory crystal, [1] a reference to the Kryptonian memory crystals from the Superman franchise) is an experimental nanostructured glass for permanently recording digital data using a femtosecond laser writing process. [2]

6. Optical computing - Wikipedia

   en.wikipedia.org/wiki/Optical_computing

   Optical computing or photonic computing uses light waves produced by lasers or incoherent sources for data processing, data storage or data communication for computing.For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers (see optical fibers).
