Archival Disc
The Archival Disc (abbreviated AD ) is an optical data carrier that is under development .
The storage medium is developed by Sony and Panasonic and traded as the successor to the Blu-ray Disc . The storage capacity will initially be 300 gigabytes, later 500 to 1000 GB are planned. The durability of the data should be longer than that of conventional optical data carriers. The intended use is primarily the long-term archiving of data.
The archival disc is written on both sides, with three data layers applied to each side. The wavelength of the laser to as the Blu-ray Disc 405 nm be at a numerical aperture of 0.85. The track spacing is 0.225 µm. The error correction is achieved by a Reed-Solomon code .
The introduction announced in Sony's 2014 white paper for summer 2015 was not adhered to. The introduction took place in spring 2016. In April 2016 a new drive was presented.
In 2017, Archival Discs were available from Panasonic with a capacity of 500 GB, which is to be increased to 1 TB.
