<P>IBM s new 5-GB Travelstar 20GN for ultra-portables sets a new record of 17.1 billion bits per square inch, the highest areal density of any hard disk drive. Greater areal density means more information can be stored in less disk space, making the drive more cost-effective to manufacture. As a result, the new IBM Travelstar drives are ideally suited for demanding, high capacity internet, digital audio, video streaming, and real-time multimedia applications - whether users are in the office or on the road. </P>
