IBM invented the first commercial disk drive in 1956 and has been leading the industry in data-storage innovation ever since. Today's hard-disk drives pack more than 5 million times more information onto every square inch of disk space than the first product. During the 1990s, data density has improved at a pace greater than 60 percent a year. Such progress has enabled us to be leaders in high-performance server and mobile drives, including the new microdrive which can store on its single 1-inch diameter disk nearly 70 times more information than the 1956 product stored on 50 two-foot diameter disks.
Our continuing improvements to the magnetic hard disk drive, as well as our investigation of alternative storage technologies, hold out the promise of extending our ability to store more information in less space, another key to building tiny, convenient portable computing devices.
