摘要： A micro-objective lens is carried on an air bearing slider with an optical passage through which the lens focuses an energy beam onto a spot on an optical data storage medium. The slider accomplishes automatic focusing. An RF coil is affixed to the slider facing the storage medium and surrounding the beam axis. The proximity of the coil lowers power switching requirements.

摘要： An optical mass storage device for use in data processing systems. Two or more lasers provide separate read and write laser beams having different wavelengths. The read and write laser beams can be orthogonally polarized. A polarizing beam splitter combines the read and write beams along a common optical path to an optical head. The head directs the combined beam to a magneto-optic storage medium. A read beam is reflected back by the medium to the common path through the head. A dichroic beam splitter disposed in the common path between the head and the polarizing splitter reflects the read beam to an optical detector. If more than one write laser is necessary, a second dichroic splitter can be used to combine the multiple write beams and the read beam.

摘要： In one aspect, an optical recording system including an optical recording medium; a light source; a focusing lens that focuses light generated by the light source to form a focused beam of light directed toward the recording medium; and a coupling medium disposed between the lens and at least one portion of the optical recording medium, the coupling medium being transparent and having a refractive index greater than one. The coupling medium facilitates optical coupling between the lens and the recording medium. In another aspect, the coupling medium is disposed so that no air gap exists in the optical path between the lens and the recording medium. In another aspect, the exit surface of the lens is disposed at a distance from the recording medium that exceeds a distance that an evanescent wave of a high angle ray of the beam of light would travel after contacting air, but the system includes coupling means for coupling the ray of light from the lens to the recording medium. In another aspect, an optical recording medium is provided with at least one layer of fluid disposed atop the recording medium, the fluid being transparent and having a refractive index greater than one.

摘要： A flying head mechanism includes a flying head, a suspension and an actuator which applies a load force through the suspension. The load force applied by the actuator is adjustable while the head is in operation. The actuator may actively control load force as part of a feedback loop which maintains the flying head at a constant flying height. One embodiment disclosed includes a voice coil actuator. In embodiments using an optical flying head, a conventional focus sensor may provide a signal indicative of flying height, since the focus signal inherently indicates flying height error.

摘要： An optical data storage medium has, on one face, a recording track and a non-recording track for high-density magneto-optical recording. The media is manufactured by sputtering magnetic material onto a surface with alternating tracks of rough and smooth textures. Alternatively, the media may be manufactured by depositing a coating of hydrogenated carbon composition and exposing the coating to ion bombardment, or by sputtering or angular deposition of magnetic material onto a corrugated surface.
