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]
Computer data storage or digital data storage is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers. [1]: 15–16 The central processing unit (CPU) of a computer is what manipulates data by performing computations.
Optical storage refers to a class of data storage systems that use light to read or write data to an underlying optical media. Although a number of optical formats have been used over time, the most common examples are optical disks like the compact disc (CD) and DVD.
High-Density Rosetta (HD-Rosetta) is a permanent data storage device which contains engraved microscopic information on a small 3-inch (7.6 cm) nickel plate. Up to 196,000 8.5×11 in (22×28 cm) pages of information can be stored onto the plate using a focused ion beam.
Fourth-generation optical discs (3D optical data storage, Holographic data storage) Research, prototyping [23] Storing and archiving data previously erased for economic reasons Blu-ray Disc, Optical storage: Li-Fi: Demos, requires standardization Laser communication in space: Machine vision: Research, prototyping, commercialization [24]
Holographic data storage is a potential technology in the area of high-capacity data storage. While magnetic and optical data storage devices rely on individual bits being stored as distinct magnetic or optical changes on the surface of the recording medium, holographic data storage records information throughout the volume of the medium and is capable of recording multiple images in the same ...
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 ...
Emerging technologies such as holographic data storage and 3D optical data storage aim to use entirely different data storage methods, but these products are in development and are not yet widely available. The earliest form is magneto-optical, which uses a magnetic field in combination with a laser to write to the medium.
