| description | PURPOSE:To enable the adaptation to a material capable of recording and erasing information, by preparing an alloy, which takes different spectral reflectances on the basis of the change in a crystal structure due to quenching and heating, by compounding Au and Al being main components in a specific ratio. CONSTITUTION:An Au-Al alloy containing 2.5-4.0wt% of Al is formed into a foil shape. This foil shows a light golden color and changes to a silver white color upon heating and air-cooling. When this silver white foil is scanned by laser beam, a golden color line can be drawn on a silver white substrate. When this golden color part is irradiated with low output laser beam, the light golden color changes to the original silver white color. That is, this alloy has different crystal structures between first temp. higher than room temp. and second temp. lower than room temp. and takes different spectral reflectances. This change in the reflectance can be discriminated in a wavelength region excepting the vicinity of about 550nm. The recording material using this alloy is enabled in the recording and erasion of information and the operation thereof can be performed repeatedly. |
