With MP3 downloads and online film
streaming it sometimes seems that the
optical disc is all but obsolete, despite
relatively niche adoption of Blu-ray. But
today Sony and Panasonic announced a
new standard for an "Archival Disc"
designed as a cheap and robust way to
store up to a terabyte of data.
The new standard
is resistant to
changes in
temperature and
humidity, dust
particles and water damage. The read-
only discs will also be extremely cheap
compared to a comparably reliable hard
disk solution of the same storage
Both companies intend to launch discs
and drives capable of storing 300GB in
summer next year, with 500GB and 1TB
discs coming later in the roadmap.
Earlier this year Facebook announced that
it was working on storage systems
involving huge cabinets full of Blu-ray
drives to store data in the event of
disasters at its more conventional storage
centres. Each disc was to be certified for
50 years of safe data storage. A robotic
arm would be able to grab certain discs
and place them on a tray where they
would be readable.
Facebook executive Jay Parikh pointed out
that each cabinet could hold a petabyte
of data, and that seven such boxes would
be capable of storing a digital copy of
every film ever made.
