New optical storage archiving systems promise 1PB optical cartridges by the 2030’s. Optical storage could be a significant contender for the digital archive market.
During recent prior year projections for digital storage and memory we have not talked much about digital storage using optical recording. Optical storage media was a big consumer technology in the past as a method for digital content distribution but there was another market for optical storage for archival storage, where cartridges of optical disc s were kept in libraries, similar to the optical libraries used for magnetic tape storage.
There is another layer of digital storage, often called the secondary storage layer where lower cost, lower performance digital storage technologies are used to store a larger amount of less active data than that stored in primary storage. Secondary storage is where nearline hard disk drives, HDDs, are used the most to store data which has value, but which does not require the performance characteristics of most enterprise SSDs.
Coughlin Associates recently wrote a white paper on current archive storage technologies, including these newer optical storage technologies Conventional optical media uses lasers with a fixed wavelength to ablate regions of the media or to change the reflective characteristics of the media to create optical features that can be encoded to store digital information. This is how CDs, DVDs and Blu-ray discs work.
Folio Photonics is a company which has developed a multilayer optical recording system for archiving applications which can result in photothermal recording similar to Blu-ray optical discs with either reflective or fluorescent recording technologies. Their technology uses photosensitive dyes dispersed in a polymer matrix to create a reflective or fluorescent optical media. This photosensitive material has a strong optical absorption at 405nm, the wavelength used for conventional Blu-ray discs.
Optera Data’s storage technology takes advantage of changes in the optical absorption/emission characteristics of its recording media at several adjacent laser frequencies during writing and then by reading these changes. These changes are referred to as spectral holes.
