IBM begins development of the floppy disk
|
1967 In 1967 IBM product manager Alan Shugart asked a small team of engineers led by David L. Noble to develop a new, inexpensive solution for loading code on the IBM 3330 mainframe. Their solution, code-named Minnow, was the first flexible magnetic storage disk, an 8-inch floppy drive with removable "memory disks". The flexible Mylar disks were coated with magnetic material that could store data. The disks had a capacity of 80 kilobytes, equivalent to approximately 3,000 punched cards. IBM shipped the first units, now called the 23FD floppy disk drive, in 1971. The technology was patented in 1972. Related information: Image:
