Matsushita continued development of the technology and released the LS-240. Other companies involved in the development of SuperDisk include Compaq and OR Technology. The idea eventually ended up at 3M, where the concept was refined and the design was licensed to established floppy drive makers Matsushita and Mitsubishi. Iomega orphaned the project around the time they decided to release the Zip drive in 1994. It is one of the last examples of floptical technology, where lasers are used to guide a magnetic head which is much smaller than those used in traditional floppy disk drives.
The design of the SuperDisk system came from an early 1990s project at Iomega.
SuperDisk worldwide ceased manufacturing in 2003. It was more successful in Asia and Australia, where the second-generation SuperDisk LS-240 drive and disk was released. The SuperDisk had little success in North America with Compaq, Gateway and Dell being three of only a few OEMs who supported it. The SuperDisk hardware was created by 3M's storage products group Imation in 1997, with manufacturing chiefly by Matsushita. The SuperDisk LS-120 is a high-speed, high-capacity alternative to the 90 mm (3.5 in), 1.44 MB floppy disk. RED - The drive eject motor allows the disk to be under computer control so that it normally will not eject until the computer has completed its read or writing tasks. YELLOW - A secondary smaller coil primarily acts to keep the head mechanism aligned parallel with the disk surface. Two voice coil servomotors move the drive heads precisely across the disk surface.īLUE - The main servo with a large coil provides the primary force to move the head mechanism. This shows the technology of the SuperDisk drive. This particular drive cannot function using USB power alone. On the right is the USB-to-ATA adapter, which plugs into an intermediate fan-out and power supply daughterboard that is inside the rear of the Mac drive's casing. The drive itself is the same size as a standard 3.5" floppy drive, but uses an ATA interface. Imation SuperDisk drive An LS-120 disk Circuit components of the external USB SuperDisk for Macintosh.
