| Sony Unveils Copyright, Audio Technologies for Memory Stick
February 24, 1999 (TOKYO) -- Sony Corp. announced technologies for copyright
protection and audio compression for Memory Stick, a small-sized storage
medium with built-in flash memory.
|Yutaka Nakagawa, corporate vice president of Sony said, "We can apply
Memory Stick to either AV electronics appliances or PC-related equipment
by using copyright protection and audio compression technology."
The announcement backs Sony's vision to adopt media that are applicable
to both AV equipment and PC peripherals.
The copyright protection technology protects copyrighted data, such as
music works, from illegal copying. Two systems were announced: Magic
Gate (tentatively named) and OpenMG (tentatively named).
Magic Gate is an authentication/encryption system embodied in a microchip.
A proprietary microchip is mounted on both Memory Stick-compliant equipment
and Memory Stick itself.
OpenMG is an authentication/encryption system for handling
copyrighted works such as music. It is composed of software, Secure
Library, and hardware, Secure Module, for keeping a key.
The audio compression technology is tentatively called ATRAC3. It corresponds
to the MD compression technology ATRAC. It allows for a long recording
time even for Memory Stick with small capacity. For instance, it allows
for one hour or longer recording in the normal mode, and two hour or
longer recording in the extension mode even for 64MB Memory Stick.
Sony also presented a road map of future Memory Stick technology.
As a first step, the company will release a new Memory Stick with a capacity
of 16MB on April 1. And then it will put a 32MB Memory Stick product
to the market in the summer of 1999 or so, and a 64MB product by the
end of the year. Further, the company reportedly aims at introduction
of 256MB Memory Stick to the market around 2001.
So far, Sony developed 3.5-inch FD for PC-related equipment and MD for
AV application equipment; both the memory/recording media have become
