SuperDisk (1997 – early 2000s)

SuperDisk (also known as LS-120, and later LS-240) was a high-capacity 3.5-inch floppy disk, introduced by Imation in 1997. Initially it has a capacity of 120 MB, but was later refined by Matsushita to hold 240 MB.

Like the Floptical disk, lasers guided the magnetic read/write head.

It was backwards compatible with 720 KB and 1.44 MB 3.5-inch floppy disks, but not with older Macintosh-formatted diskettes. Iomega’s Zip Drive had also been on the market for several years when it was launched, and there was little interest in the SuperDisk system, especially when prices of CD-R and CD-RW drives and USB flash drives fell, and it was discontinued in the early 2000s.
