Purpose of the development: Made sapphire discs that can be used as optical media for storage, distribution and archiving of digital information.

Recommended application field: Recording of digital information.

Technical characteristic: Produced in the past and is currently testing the sapphire discs satisfy the requirements for recording information and have the following specifications: - Diameter 80 mm, thickness 0.7 mm; - Crystallographic orientation (0001) ± 5 arcmin .; - The half-width of the rocking curve (FWHM) - 6-9 arcsec .; - Dislocation density of <10,000 cm minus 2 degrees; - The lack of low-angle boundaries of blocks; - Surface roughness (Ra) 0.2-0.3 nm; - Optical purity 20/10.

Advantages over analogues: Sapphire optical disc can store information for tens of thousands of years.

The development stage readiness: Introduced in production

Description of the development:
()
Due to the unique properties of sapphire development will solve the problem of long-term storage of information. Sapphire can withstand high temperatures (up to 2000 ° C) and is almost equal in hardness to diamond.
