<P> Work on a drive that led to the world 's first floppy disk and disk drive began in 1967 at a San Jose ( CA ) IBM facility , and introduced into the market in an 8 - inch format in 1972 . The more conveniently sized 51⁄4 - inch disks were introduced in 1976 , and became almost universal on dedicated word processing systems and personal computers . This format was more slowly replaced by the 31⁄2 - inch format , first introduced in 1982 . There was a significant period where both were popular . A number of other variant sizes were introduced over time , with limited market success . </P>
