The recent introduction of Sony's 14X MO media provides up to 9.1GB of storage capacity and 6 MB/s data transmission rates. The special features of the 5.25-inch MO disk, namely its high-speed random access and massive storage capacity, make it suitable for a wide variety of applications. In addition to its use as an external storage device on PCs and work stations, it may also be used for LAN and Web servers, computer graphics, CAD/CAM, storage of X- ray and ultra- sound wave images, etc., non- linear audio/video editing, and document archiving by government offices and libraries. It may also be used for large-scale libraries and juke boxes that require high-speed disk changes.
