る状態を作る方式が一般的である。Optical storage systems are attracting attention because they can achieve higher storage densities than magnetic storage systems. Optical storage systems record information by irradiating a TeC recording film formed on an acrylic resin substrate with a laser beam in response to a signal and making holes in the recording film in thermal mode. A common method is to use a TaOx film or the like to change crystallinity to wandering crystallinity in a thermal mode by laser beam irradiation, thereby creating states with different light reflectances.
