In late July of 2013, Sony and Panasonic signed a “basic agreement” to develop “standard professional-use next-generation optical discs.” Yesterday, the two companies announced the outcome of this agreement, the Archival Optical Disc.
Sony and Panasonic are planning systems with a recording capacity of 300 GB per disc from summer 2015, onwards. Further plans on expansion include increasing the recording capacity per disc to 500 GB and eventually 1 TB.
Could this be the answer for photographers? It really all boils down to cost. I just hope disc manufacturers are held to a high media quality standard, because there is no point of an archival disc format if the disc’s fail after only a few years.
1000 GB per disc is probably a couple of years away, but how tantalizing? By comparison a 1TB disc would have the same capacity as 40 Blu-Ray disc’s, 220 DVD’s, or 1,538 CD’s.
Will those hard drives on your shelf soon be replaced with optical disks? Only time will tell.
