技術摘要 / Our Technology:
本創作係為一種可重複讀寫型氧化鋅式近場光碟片,其結構係由一透光基板以及披覆於透光基板上之複數薄膜層所組成,此複數薄膜層包含一層可產生侷域近場光學作用之氧化鋅奈米薄膜層,一層可重複讀寫之記錄薄膜層,以及保護和維持整體薄膜結構特性之第一、第二、第三透光介電質薄膜層;藉此構成,使可產生侷域近場光學作用之氧化鋅奈米薄膜層,維持在可重複讀寫之記錄薄膜層的近場光學作用範圍內,來執行超高密度近場光學記錄之功能。
This invention is a rewritable near-field optical medium using a zinc oxide nano-structured thin film as the localized near-field interaction layer. This rewritable near-field optical medium is a multilayered body at least comprising: (a) a substrate of transparent material; (b) a first protective and spacer layer formed on one surface of the substrate, which Is made of transparent dielectric material; (c) a zinc oxide nano-structured thin film which is capable of causing localized near-field optical interactions; (d) a second protective and spacer layer formed on the localized near-field optical interaction layer, which is also made of transparent dielectric material; (e) a rewritable recording layer; (f) a third protective and spacer layer formed on the rewritable recording layer, which is also made of transparent dielectric material. Ultrahigh density near-field optical recording can be achieved by the localized near-field optical Interactions of the zinc oxide nanostructured thin film that is in the near-field region of the rewritable recording layer.
