Sony, Panasonic Partner on Archival Disk Storage Standard
The two companies aim to launch systems with a recording capacity of 300GB per disc from summer 2015 onwards.Major technology companies Sony and Panasonic are partnering to offer organizations Archival Disc, a new standard for professional-use, next-generation optical discs, with the objective of expanding the market for long-term digital data storage. The two companies aim to launch systems with a recording capacity of 300GB per disc from summer 2015 onwards. In addition, both companies plan to leverage their respective technologies to further expand the recording capacity per disc to 500GB and 1TB. In anticipation that optical discs will need to accommodate much larger volumes of storage going forward, particularly given the anticipated future growth in the archive market, Sony and Panasonic have been engaged in the joint development of a standard for professional use, next-generation optical discs. "Optical discs have excellent properties to protect themselves against the environment, such as dust-resistance and water-resistance, and can also withstand changes in temperature and humidity when stored," a joint press statement explained. "They also allow inter-generational compatibility between different formats, ensuring that data can continue to be read even as formats evolve."
Crosstalk cancellation technology, which electrically removes crosstalk from the adjacent tracks that increase as the track pitch becomes narrower, to achieve high-quality playback performance, and high-order Partial Response Maximum Likelihood (PRML) signal processing technology, a signal processing technology that improves reproduction performance by allowing inter-symbol interference, have been employed to achieve both larger capacity and higher playback signal quality.
