Sony develops paper DVD
April 20, 2004
TOKYO — Electronics giant Sony and another Japanese company have
developed a "paper disc" that can record more than two hours of
high-definition images and be destroyed with scissors for foolproof
data security, officials said Monday.
The 25-gigabite Blu-ray optical disc is 51 percent paper and was
developed jointly with Toppan Printing Co. Ltd. of Japan.
"Since a paper disc can be cut by scissors easily, it is simple
to preserve data security when disposing of the disc," Toppan
managing director Hideaki Kawai said in a joint statement with
Masanobu Yamamoto, senior managing director at optical disc
development division of Sony, said the firms were able to use paper
in the new disc as the Blu-ray technology does not require laser
light to travel through the substrate.
The technical details of how it is possible to use paper as a
data storage disc would be disclosed Tuesday at a conference in
Monterey, California, according to the statement.
The combination of paper material and printing technology is
also expected to lead to a reduction in cost per disc and will
expand usage, the two partners said. It has yet to be undecided
when the disc will be commercially available.
The use of paper in electronics products is not new for Sony.
In 1950 when Japan was still struggling to rise from the ashes
of World War II, Sony, then called Tokyo Tsushin Kogyo, made
magnetic tapes using a similar grade of paper to that used for
Sony used racoon hair brushes to daub magnetic powder over the
paper to produce what it cally "SONI TAPE", starting its history as
an audio-video products maker.
The Blu-ray disc format allows high-capacity optical-disc
storage to be used for such technologies as high-definition
A group of manufacturers was set up in 2002 to promote a common
standard for the disc format comprising Dell Inc., Hewlett-Packard,
Hitachi, LG Electronics, Matsushita Electronics Industrial,
Mitsubishi Electric Corp, Pioneer Corp, Royal Philips Electronics,
Samsung Electronics, Sharp Corp, Sony Corp and Thomson. –Sapa-AFP
