Imation 120 MB SuperDisk diskette

Alternatively called an LS-120 and LS-240, the SuperDisk is a disk drive and diskette introduced by 3M, which became Imation. The drive was popular with OEM (original equipment manufacturer) computers, such as Compaq and Packard Bell.

The original SuperDisk (shown right) could hold 120 MB on a single disk the same size as a traditional 1.44 MB floppy diskette. Later, SuperDisks were capable of holding 240 MB. The SuperDisk drive was also backward compatible with 1.44 MB disks. Its available interfaces were IDE/ATAPI, parallel port, SCSI (small computer system interface), and USB (universal serial bus).

The SuperDisk did not become popular primarily because of the Iomega Zip drive, which had already gained success before the SuperDisk was released. Today, the SuperDisk and Zip drive are not used because of technologies like the CD-R (compact disc recordable) disc and USB thumb drives.


The SuperDisk should not be confused with the SuperDrive.
