Positioning device for a sensing head of an optical data storage system |
摘要 |
A positioning device for optical data storage which has an optical system for generating a polarized, parallel laser light beam and for receiving gated out reflected light beams for evaluation and a sensing head which is radially displaceable relative to a storage disk characterized by the optical system being contained in a rigid frame mechanically decoupled from the sensing head. The system includes a pivotably mounted deflection mirror which enables fine positioning. The sensing head will include an imaging system for focussing the laser beam onto the storage disk which is resiliently hinged to the sensing head so that it is deflectable in a vertical direction for readjustment of the focussing independent of radial motion of the sensing head.
