In 1967, at an IBM facility in San Jose, California, work began on a drive that led to the world's first floppy disk and disk drive. [1] It was introduced into the market in an 8-inch (20 cm) format in 1971. The more conveniently sized 5¼-inch disks were introduced in 1976, and became almost universal on dedicated word processing systems and ...
Invented by IBM engineers led by Alan Shugart, the first disks were designed for loading microcodes into the controller of the Merlin (IBM 3330) disk pack file, a 100 MB storage device. So, in effect, the first floppies were used to fill another type of data storage device.
Floppy disks store digital data which can be read and written when the disk is inserted into a floppy disk drive (FDD) connected to or inside a computer or other device. [2] The first floppy disks, invented and made by IBM in 1971, [3] had a disk diameter of 8 inches (203.2 mm). [4]
floppy disk, magnetic storage medium used with late 20th-century computers. Floppy disks were popular from the 1970s until the late 1990s, when they were supplanted by the increasing use of e-mail attachments and other means to transfer files from computer to computer.
IBM began selling floppy disk drives in 1971 and received US patents for the drive and floppy disk in 1972. The floppy disk made it possible to easily load software and updates onto mainframe computers and quickly became the most widely used storage medium for small systems.
Shugart joined Memorex in 1969 as Vice President of its Equipment Division and led the development of its 3660 (compatible with IBM 2314) and 3670 (compatible with IBM 3330) disk storage subsystems. His team also developed the Memorex 650, one of the first commercially available floppy disk drives.
The story of the Floppy Disk began in the late 1960s when IBM introduced the first-ever floppy disk, an 8-inch marvel that would soon set the stage for a revolution in data storage. However, the advent of the more compact and versatile 5.25-inch and 3.5-inch formats in the late 1970s and 1980s marked the Floppy Disk era.
