The 5 1/4" flexible disk drive was introduced
The 5 1/4" flexible disk drive and diskette were introduced by Shugart Associates in 1976. This was the result of a request by Wang Laboratories to produce a disk drive small enough to use with a desktop computer, since 8" floppy drives were considered too large for that purpose. By 1978, more than 10 manufacturers were producing 5 1/4" floppy drives.
