Abstract
【解決手段】 記録中にマルチ・スタック光学記憶媒体(20)の入射面(16)を介して入射するフォーカスされた放射ビーム(19)を使用し、書換え可能な状態にして記録するための、マルチ・スタック光学データ記憶媒体(20)について記述している。前記媒体(20)は、第1の相変化型記録層(6)を含む第1の記録スタック(2) L0の側面に置かれる基板(1)を含む。第1の記録スタック(2)は、入射面(16)から最も離れた位置に存在する。さらなる相変化型記録層(12)を含む少なくとも1つのさらなる記録スタック(3)Lnは、第1の記録スタック(2) よりも入射面(16)の近くに存在する。透明スペーサ層(9)は、記録スタック(2, 3)の間に存在する。さらなる記録層(12)は、実質上、原子百分率式GexSbyTez(0 <x < 15, 50< y < 80, 10< z < 30, x + y + z = 100)によって定義される合金でできている。この層(12)は、また、4 nm〜12 nmの範囲から選択される厚さを有し、さらなる記録層(12)と接触し、5 nm未満の厚さを有する、少なくとも1つの透明結晶化促進層(11’, 13’)を有する。Lnスタック(3)の記録層(12)の低い結晶化時間と組み合わされた高い光学透過は、少なくとも12 m/sの線形記録速度を伴うマルチ・スタック高速記録に適した媒体(20)を製造することにより達成される。

を備えるマルチ・スタック光学データ記憶媒体に関する。
I(160)-N(2)-P(5)-N(2)-I(5)-M(6)-I(80)(記号Iは、誘電層11または13を表し、Nは、結晶化促進層11’または13’を表し、Pは、記録層12を表し、Mは、金属層14を表し、また、ブラケット間の数は、各層を nm単位で表す)。この設計では、以下のような、光学透過(T)、反射(R)、およびL1スタック3のコントラスト値が、次のように得られる:
Tc = 0.352 Ta = 0.531 Rc = 0.145 Ra = 0.028、cおよびaは、相を表示する、すなわち、記録層12の結晶相または非晶相を示す。コントラスト= (Rc - Ra)/Rc = 0.807。
相変化記録層6および12は、適切なターゲットの真空蒸着またはスパッタリングによって、基板に堆積される。このようにして堆積させた層は、非晶質であり、かつ、イニシャライザと呼ばれる特殊なレコーダにより、初期化、すなわち結晶化される。さらなる層は、スペーサ層9およびカバー層15を除いて、適切なターゲットの真空蒸着またはスパッタによっても設けられる。情報記録用の放射ビーム19は、透明カバー層15を介して、記録層6または12に入射する。透明カバー層15は、0.1 mmの厚さを有し、スピンコーティングによって設けられた紫外線硬化型樹でできている。カバー層15は、また、圧力高感度接着剤(PSA)を含むプラスチック・シートを適用することによって、設けることもできる。
