ABSTRACT:
A method and an apparatus for recording at least two multiplexed holograms. Either an object beam or a reference beam is reflected from an aspherical reflecting surface. Either the reference beam impinging on a recording media at the selected storage location or the object beam impinging on the recording media at the selected storage location is rotated through a selected azimuthal angle about an axis that passes through a plane defined by the intersection of the object beam and the reference beam in the recording media, wherein an angle between the object beam and the reference beam impinging on the recording media is preserved.
