HOLE IN ONE
Peter Vettiger and his team of researchers at IBM's micro and 
nanomechanics group in Zurich are in the process of creating the 
world's smallest data storage disks.  With a certain number of 
cantilevers, Vettiger's new product, called the Millipede, can 
store more than 100 times more data on a polymer-coated disk 
than today's magnetic hard disks can store.  The Millipede can 
read and write data at roughly 100 Mbps, and can store as much 
as 3000 GB of data on one square centimeter.  Such a microscopic
mechanism may have a few problems, one being that an assembly 
has not yet been built to fit into a real computer's disk drive.  
Other problems relate to the long-term durability of the moving 
parts, and to the fact that the polymer surface that contains the 
data only moves in a straight line and has not yet been formed 
into a disk.  However, IBM says these problems should be solved 
soon, and that it will not be too long before the product is 
available on the market.
