Terastor

(Terastor, Inc., San Jose, CA) A company that was developing a next-generation hard disk. Founded in 1995 and disbanded in 2000, advances in regular hard disks kept it from gaining the edge it was looking for. Terastor's Near Field Recording (NFR) used a patented Solid Immersion Lens (SIL) from Stanford University that focused the laser beam down to a tiny spot. It employed magneto-optic recording, but placed magnetic and optical elements on the same head rather than on opposite sides of the platter. See magneto-optic disk.
