ABSTRACT:
An optical recording system in which the optical head is operated in physical contact with the surface of the optical recording medium during system operation at a selected operating speed. The optical head includes one or more optical elements mounted on a substrate which is in physical, sliding contact with the recording medium. The substrate is fabricated from a crystalline material which has a non-linear load versus friction characteristic in the negative load region. When the head is in sliding contact with the recording medium surface, a restoring force is generated which maintains the optical head in physical contact with the recording medium overcoming any lifting forces generated by the moving air layer adjacent the recording medium surface. This allows the head to be operated with a negative external load applied. Utilizing the optical head having the objective lens mounted on the substrate in close proximity to the recording medium surface allows high density recording to be achieved without the requirement of an electro-mechanical servo system to provide beam focusing for the system.
