島状金属薄膜を用いた波長多重記録媒体の試作  [in Japanese] Fabrication of Multiwavelength Optical Data Storage Media Using Metal Island Films  [in Japanese]

Abstract

島状金属薄膜は共鳴吸収波長帯で反射率・吸収率がともに高いため, 光記録媒体として用いることができる.また, 適当な成膜条件を選択することによって比較的狭帯域な記録媒体を得ることができ, 薄膜を構成する材料によって共鳴吸収波長を選ぶことができる.本稿ではこのような特徴を利用し, 島状金属薄膜を追記型波長多重記録媒体として用いることを試みた結果について報告する.波長490 nmと810 nmに対応した2種類の島状金属薄膜を選択し, 波長多重記録媒体の試作を行い, その原理確認実験に成功した.

As metal island films have large reflectance and absorptance at resonance wavelengths, the metal island films can be used as optical data storage media. The metal island films with relatively narrow bandwidth and desirable resonance wavelength can easily be fabricated by the choice of fabricating conditions and metals. In this paper, we propose and investigate write-once multiwavelength optical data storage media using the metal island films. We have chosen two metal island films as recording layers for 490 nm and 810 nm and have fabricated the multiwavelength optical data storage media using them. We have successfully confirmed the basic operations.
