Optical head using micro-machined elements
An optical head utilizes a micro-machined element in combination with a light source and a lens to write and read data onto a storage disk. The micro-machined element may include a steerable micro-machined mirror or a micro-actuator. A beam of laser light transmitted from the light source to the optical head and a reflected light from the storage disk is altered by a movement of the micro-machined element. In this manner a focused optical spot is scanned back and forth in a direction which is approximately parallel to the radial direction of the storage disk.
