Sony And Panasonic's 300GB - 1TB 'Archival Disc' Standard




12th March 2014
Sony, in a joint venture with Panasonic have announced their new 'Archival Disc' standard designed for professional long term storage.

300GB to 1TB
The new standard will start with 300GB optical discs but with eventually reach a staggering size of 1TB. They will use Crosstalk cancellation technology and PRML signal processing technology to achieve the higher capacities while keeping an optimal playback signal quality. The use of optical discs is preferred due to their backward compatibility and their ability to withstand temperature and humidity variations without affecting the stored media.

Blu Ray
This collaboration seems similar to the one that Sony and Panasonic entered into when developing Blu Ray technology. Some would call that a success and others would point to the lack of take up from DVD and call it a failure. However the plan this time seems to be to promote this as a business storage medium, something which is more likely to be successful as data storage and archiving has been growing at a phenomenal rate in recent years.

Disc Size 300GB - 1TB
Optical Parameter Wavelength λ=405 nanometres, Numerical Aperture NA=0.85
Disc Configuration 3 layers per side, double sided
