Alternatively referred to as an LS-120 and LS-240, the SuperDisk is a disk drive and diskette introduced by 3M, which later became Imation. The drive was most popular with OEM computers, such as Compaq and Packard Bell computers.
The original SuperDisk (shown in the picture to the right) is capable of holding 120 MB on a single disk the same size of 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, and USB.
The SuperDisk did not become very popular primarily because of the Iomega Zip drive, which had already gained success before the SuperDisk was released. Today, neither the SuperDisk or the Zip drive are used because of technology like the CD-R disc and USB thumb drives.
The SuperDisk should not be confused with the SuperDrive.
