| In
as little as five years compact discs may be replaced by a new
generation of paper-thin, fingertip-sized memory tabs with no
moving parts. While current CDs require a moving laser and motor
drive and hold about a half of a gigabyte, the new devices could
store more than a gigabyte of information and require no moving
parts to operate.
The one-cubic-centimeter memory block, based on a combination
of silicon films and a cheap plastic polymer known as PEDOT,
would be faster and easier to operate than a CD. Scientists
say the device could be manufactured cheaply enough so it
would likely be a one-time use item.
