A type of disk drive that combines magnetic disk technologies with CD-ROM technologies. Like floppy disks, they are removable; however, they are faster than floppies and can store more than 200 megabytes.

A drive that combines laser and magnetic technology to create high-capacity erasable storage.

storage: A combination of optical and magnetic storage technology. The disk itself is magnetic, but a laser beam is used to encode the surface. These drives have much greater capacity because the light beam can be focused much tighter than a magnetic field.
