Flying optical head with dynamic mirror |
摘要 |
A magneto-optical flying head utilizes a steerable mirror in combination with a light source and a lens to write and read data onto a magneto-optical storage disk. A beam of laser light transmitted from the light source to the optical head is reflected onto a steerable micro-machined folding mirror. The reflected light from the folding mirror is directed through an embedded micro-objective GRIN lens. Fine tracking and short seeks to adjacent tracks are performed by rotating the mirror about an axis of rotation. In this way a focus spot is scanned back and forth in a direction which is approximately parallel to the radial direction of the storage disk.
