Komag, Inc.

Komag, Inc., is the world's leading manufacturer of magnetic thin-film disks for computer hard drives. The company's most important product is sputtered thin-film media, which are data storage components made by depositing successive layers of magnetic material on a disk, then covering it with a protective overcoat. The entire sputtering process must be done in a vacuum. Using this technique, Komag makes and markets thin-film products for several types of disk drives.
