• What is the history of the three and a half inch floppy disk?

  The three and a half inch floppy disk was introduced by Sony in 1982 and remained in common use for at least two decades. It was a smaller and more user-friendly version of the earlier eight-inch floppy disks, with a unique shape that ensured correct insertion into the drive. IBM referred to them as diskettes, which became the industry standard term, although most people commonly called them floppy disks. These diskettes were more durable than their predecessors, with a hard plastic shell and protective shutter that prevented damage from greasy fingers or accidental creasing.

• How did the three and a half inch diskettes differ from the five and a quarter inch disks?

  Unlike five and a quarter inch disks, three and a half inch diskettes did not require a latch or door to be closed when inserted; they automatically locked into place. Additionally, three and a half inch diskettes were more durable, with a hard plastic shell and protective shutter that prevented damage from greasy fingers or accidental creasing. The write protect feature on three and a half inch diskettes was user-friendly, with a built-in sliding tab for enabling or disabling writing to the disk, eliminating the need for stick-on labels.
