ABSTRACT:
A search method of efficiently retrieving information is provided.A search light21is generated from a search condition (S1). The search light is irradiated onto a hologram104arecorded in a hologram recording layer104(S2). When the search light interferes with the hologram and a reproduction light is generated, address information of the hologram from which the reproduction light is generated is identified using an address light23that reads the address information. The identified address light is recorded (S3). When the search light does not generate the reproduction light from the hologram, the search light is irradiated onto another hologram104brecorded in the hologram recording layer.
