Abstract
A new optical recording medium capable of reducing the burden in erasing data in the optical recording medium is provided. The optical recording medium includes an organic pigment recording layer 12 and a light reflecting layer 14, which are at least laminated on a substrate 11, wherein a photocatalyst layer 13 is formed in contact with the organic pigment recording layer 12.
Claims6
An optical recording medium comprising an organic pigment recording layer and a light reflecting layer, which are at least laminated on a substrate, wherein a photocatalyst layer is formed in contact with the organic pigment recording layer.
An erasure apparatus that erases information recorded in an optical recording medium comprising an organic pigment recording layer and a light reflecting layer, which are at least laminated on a substrate, wherein a photocatalyst layer is formed in contact with the organic pigment recording layer, the erasure apparatus comprising erasing device configured to erase the information recorded in the organic pigment recording layer by irradiating the optical recording medium with light whereby the photocatalyst layer demonstrates oxidation.
An erasure method for erasing information recorded in an optical recording medium including an organic pigment recording layer and a light reflecting layer, which are at least laminated on a substrate, wherein a photocatalyst layer is formed in contact with the organic pigment recording layer, the erasure method comprising irradiating the optical recording medium with light whereby the photocatalyst layer demonstrates oxidation.
