Abstract

According to one aspect a method for manufacturing a holographic storage medium includes providing one or more data masks (122) with data to be recorded, illuminating the one or more data masks onto the medium with a plane wave object beam (116) from a laser light source (110) operating at a record wavelength, propagating a reference beam (114) at an incident angle to the medium (124) to record the one or more data masks on the medium, and altering the incident angle of the reference beam for each of the one or more data masks, wherein each of the one or more data masks recorded on said medium can be read bit by bit using a laser light source operating in a readout range of wavelengths different from the record wavelength.
