An information recording medium, comprising:
- a first insulating member,
- first and second electrodes formed in one plane of said first insulating member, and
- a first conductive layer including an electrochromic material providing continuity with said first and second electrodes,
- wherein the gap between said first and second electrodes is insulated.
An information recording medium, comprising:
- an insulating member,
- first, second, and third electrodes formed in one plane of said second insulating member, and
- a conductive layer including an electrochromic material providing continuity with the gap between the first and second electrodes and the gap between the first and third electrodes,
- wherein the gaps between said first electrode, said second electrode, and third electrode are insulated from each other.
An information recording method of the information recording device for recording information on an information recording medium and for reading information from the information recording medium which comprises an insulating member, first and second electrodes formed in one plane of the insulating member, and a conductive layer including an electrochromic material providing continuity with said first and second electrodes, the method comprising the steps of:
- coloring said conductive layer by applying a voltage to the gap between said first and second electrodes for the information recording medium in which the gap between said first and second electrodes is insulated;
- and
- recording information by irradiating light to said colored conductive layer.
