Abstract

Traditionally, optical storage has been unable to compete with magnetic storage in the hard disk drive market because multiple heads and disks could not be integrated in a small volume. Optically-assisted Winchester technology overcomes this problem using a fiber-optic delivery system to carry light to multiple recording heads, each of which utilizes several micro-optical components. The small size of the recording head presents design challenges difference from those usually faced in the optical storage industry.
