What is LS-120 Drive?
Imation SuperDisk, also called the LS-120, this is a 3M spin-off. Capacity is 120MB, and both desktop and portable versions are now available. The advantage of the LS-120 is that it can read your existing 1.44 floppy disks as well as its own 120MB disks. There are several second-source makers, and the drive can be built on existing floppy disk drive production lines. LS-120 drives, uses a laser to position its read/write heads over very fine servo tracks etched into the surface of the disk platter. Since the laser is so precise, LS-120 disks feature 2,490 data tracks per inch, compared with 135 for floppy disks. In this way, LS-120 disks accommodate much more data in the same surface area.
