ABSTRACT:
A data recording and retrieval system wherein a beam of coherent radiation is optically formed into an intense spot and deflected by first and second deflecting means to impinge upon a storage medium. The beam is spot-focused by a lens system which includes a multiple lens array, and selectively deflected by a pair of mirrors through a particular lenslet of the multiple-lens array to one of a plurality of storage fields of the recording medium. When the storage field is selected, a second deflection system produces a randomly selectable X-Y deflection of the beam, within the area of the preselected storage field. The multiple lens array provides a plurality of lenslets, each lenslet of the array corresponding with a different one of the plurality of storage fields within a storage area of the recording medium. Also included are means for illuminating a selected one of the areas of the storage medium and detector means for sensing data recorded on the selected storage field projected through a corresonding lenslet of the multiple lens array to the detector means.
