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.

Optical head using micro-machined elements

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.

Flying optical head with dynamic mirror

An optical microswitch for use with a laser beam comprising a support body and first and second output fibers carried by the body. An electrostatic microactuator is carried by the body and extends in a plane. A micromirror is disposed out of the plane. The microactuator has a mirror holder coupled to the micromirror and at least one comb drive assembly coupled to the mirror holder for driving the micromirror about an axis of rotation extending perpendicular to the plane between a first position for reflecting the laser beam to the first output fiber and a second position for reflecting the laser beam to the second output fiber.

A system for maximum magneto-optical data storage system is provided. The system utilizes double-sided first surface magnetically-induced super resolution storage media to provide the ability to access a data mark from a plurality of data marks within an optical spot size of an impinging optical beam of light.

Magneto-optical system utilizing MSR media

An optical system and method for selective transmission of light between a source of light and a set of storage disks along an optical path that includes at least one individual optical fiber. In an optical system and method that uses a magneto-optical storage medium, single-mode polarization maintaining optical fibers and a compensator may be included. Alternatively, the optical system and method may include an optical switch.
