An optical or magneto-optic head and method of making the same |
摘要 |
A method for forming a novel head used in magneto-optic or optical disks comprises the steps of forming a diffractive lens on one side of a glass substrate and forming air bearing surface rails on a second side of said glass substrate. The glass substrate is then cut into separate heads. In this way, many magneto-optic or optical heads can be formed simultaneously without incurring the expense of bonding lenses onto a slider. In one embodiment, coils are deposited on the substrate to generate a magnetic field during magneto-optic write operations. In another embodiment, a glass wafer having diffractive lenses formed thereon is bonded to a silicon spacer structure. The glass lenses are used to define a waveguide structure on a transparent layer on the bottom of the silicon spacer structure. <IMAGE> |
