Technofile : Mighty disc

IBM has broken its own memory storage record with a hard-disc drive that can
store 1.8 billion bits of data per square centimetre. The new disc stores more
than double the previous record set by IBM a year ago. Although the new drive is
only a laboratory prototype, the company hopes to produce a commercial version
by 2001. If so, analysts expect the cost of hard-disc storage to fall by a
third.
