发明名称 A gantry for positioning a read/write head of a holographic information storage system
摘要 A holographic storage system includes a storage media in the form of a disk that is operable to incrementally rotate under a moveable optics system contained in a gantry. The gantry reciprocates along the radial axis of the media in response to a drive mechanism. A laser is operable to direct a beam to a mirror that reflects the light beam along the reciprocating axis of the gantry. The gantry contains a spatial light modulator which is operable to receive the incoming light beam and transform it through a transform lens down to a storage location on the surface of the storage media. A reference beam is reflected from a reflecting surface at a predetermined angle and directed to the storage location by an elliptical mirror to interfere with the data beam and perform a record operation. During data reconstruction, when the reference beam is generated a reconstructed data beam is directed toward the reconstruction optics and a detector array. The detector array is also contained on the gantry.
