A silver island film has been investigated as write-once optical storage media for commercially available 800 nm-laser diodes. The silver island film deposited at a room temperature exhibits broad resonance-type reflection characteristics in the wide wavelength regions from 430 to 850 nm due to the resonance of free electrons in silver islands. By heating the film at a temperature of >120 degree(s)C, the reflection drastically lowers in the longer wavelength region near 800 nm from the change of the resonance characteristics of the free electrons caused by the thermal deformation of the silver islands. Laser writing on the silver island films with the 820 nm-laser diode is demonstrated. In addition, it is shown that the silver island films can also be used for the shorter wavelength region of 450-500 nm since the resonance peak disappears by heating at the temperature of >500 degree(s)C from the oxidization of the silver islands.
