The Floppy Disk Is Introduced for Storing Data Used by Computers (Great Events from History II: Science and Technology Series)
Article abstract: Engineers at IBM Corporation’s San Jose laboratory developed the disk drive, an inexpensive means of storing data in computer applications.
Summary of Event
When the IBM Corporation decided to concentrate on the development of computers for business use in the 1950’s, it faced a problem that had troubled the earliest computer designers: how to store data reliably and inexpensively both during immediate processing and for later use. In the early days of electro-mechanical computation (the early 1940’s), the English inventor Andrew D. Booth produced spinning paper disks on which he stored data by means of punched holes, only to abandon the idea because of the insurmountable engineering problems he foresaw. To work reliably, such disks would have to rotate quickly and in a stable fashion; in order to record enough data to be efficient and therefore economically feasible, the read/write head—the device that would encode and decode data on the spinning disk—would have to hover very close to the disc surface without actually touching it. The project was abandoned when these requirements were deemed impossible.
An alternative technology—punched...
