Method for recording and reproducing a holographic read only recording medium, and holographic read only recording medium

摘要

A recording signal beam and a recording reference beam are irradiated onto a first surface of a holographic recording medium to write an information as an interference pattern therein. Next, a reflective layer is provided on a second surface opposite to the first surface of the holographic recording medium such that the reflective layer is adhered with the second surface, and a reproducing reference beam is irradiated onto the first surface of the holographic recording medium so as to read a signal beam which is reflected at the reflective layer and reproduced from the holographic recording medium.

1. A method for recording and reproducing a holographic read only recording medium, comprising the steps of:
irradiating a recording signal beam and a recording reference beam onto a first surface of a holographic recording medium to write an information as an interference pattern therein; providing a reflective layer on a second surface opposite to said first surface of said holographic recording medium such that said reflective layer is adhered with said second surface; irradiating a reproducing reference beam onto said first surface of said holographic recording medium and reading a signal beam which is reflected at said reflective layer and reproduced from said holographic recording medium; wherein said holographic recording medium is provided between a transparent substrate and an anti-reflector such that said first surface is located in a side of said transparent substrate and said anti-reflector is removed after writing said information and before providing said reflective layer, wherein said reflective layer is adhered and joined with said second surface of said holographic recording medium via an adhesive agent; and wherein a thickness of said adhesive agent is set within a range of 0.1 μm to 200 μm.
