There is a possibility that the use of an ultraviolet (UV) spectrum can enhance the cost, size and speed of storage media and this is why current research within the field is focusing on it. The trend of increasing the amount of data and the quality of video content needed for cheap and efficient storage is being followed by it.
Recently, the news that the development of a solid-state laser operating in the ultraviolet spectrum has progressed was released by UC Riverside scientists. Radiation in the electromagnetic spectrum is emitted at the 405 nanometer wavelength by the blu-ray lasers of today, and this is where we see blue.
Researchers from the Riverside University of California showed an ultraviolet laser in a demonstration, which had a slightly higher 385 nanometers frequency. Dr. Richard G. Zech, a renowned expert in technology related to optical storage, expressed his opinion on the findings.
He expressed that the UV light in optical storage developed for commercial use would need to have a wavelength of at least 200 nanometers. However, if such wavelengths are used, the optical media would have a storage capacity of 100 GB per layer. This would mean that Blu-Ray services could be created and optimized quite easily.
However, in order to use UV light at a wavelength of 200 nanometers a device capable of emitting it will have to be created. The fact that overtime majority of plastics are destroyed by UV radiation is also a hindrance for UV optical technology. This is why creating optical discs that can store UV information for a long time will be quite challenging.
So, the difficulties in the way of UV optical technology are apparent, but researchers continue to show interest in creating optical discs capable of storing large capacities of UV information. So, there are several difficulties barring the way of UV optical technology, but researchers continue to show interest in creating optical discs capable of storing large capacities of UV information.
Currently, a substantial storage capacity is needed for storing HD content in Blu-Ray discs. About 25 GB of data can be stored in a single-layer Blu-Ray and double the data can be stored in double layer discs.
NHK in Japan has been doing work on ultra high resolution or super high-resolution video that raises the resolution of videos from 1080 up to 2060 or even 4230. Storing a 2 hour movie with such a high-resolution would require hundreds of GB storage space in a Blu-Ray disc.
It will take a couple of years for super high definition video to be available on the market, but certain consumer video technologies might have this technology as the decade ends. In order to sell this high-resolution video footage, some way of storing such video in an economical and efficient manner will have to be figured out by distributors and retailers. Today, it barely takes a dollar to make Blu-Ray discs and the rest of their price goes to profits.
Over the past decade or so, the sales of most optical discs have significantly decreased and only Blu-Ray discs seem to be selling splendidly. One reason behind this is that people are able to access content via the internet easily using high-speed internet connections, which also cuts down the cost.
Considering the fact of how UV optical technology might affect the size of the next-generation storage media, the future of physical media seems to be bright.
