Abstract
【解決手段】記録光の照射により屈折率が変化する複数の記録層14と、当該複数の記録層14の間に設けられる中間層15とを備えた光情報記録媒体10である。記録層14と中間層15とは、互いに屈折率が異なり、記録層14と中間層15の界面のうち、記録層14と、当該記録層14に対し記録光が入射される側で隣接する中間層15との界面(前側界面19)は、記録層14と中間層15が混じり合うことで徐々に屈折率が変化している。
【選択図】図1
Description
本発明の一実施形態に係る光情報記録媒体10は、図1に示すように、基板11と、サーボ信号層12と、複数の記録層14と複数の中間層15と、カバー層16とを備えてなる。
Rは置換基を表し、置換基としては、特に限定されず、具体的には、アルキル基、アルコキシ基、アルコキシアルキル基、アリールオキシ基、などが挙げられる。mは0以上4以下の整数を表す。
0.001<((n2−n1)/(n2+n1))2<0.04
を満たすのが望ましい。
所望の記録層14に情報を記録するとき、その記録層14に、記録すべき情報に応じて出力が変調されたレーザ光(記録光RB)を照射する。記録層14が、多光子吸収化合物を主たる記録色素として有する場合、このレーザ光には、ピークパワーを大きくできるパルスレーザ光を用いるとよい。そして、記録光RBの焦点の位置は、図5に示すように、レーザ光の奥側界面18から記録光RBの入射側にω0<d<3ω0を満たすオフセット量dだけずらすのがよい。ここでのω0は、図3に示した記録スポットMの半径である。この半径ω0は、図3の左の記録スポットMのように記録光RBと光情報記録媒体10を相対的に移動させていないときの円形状のスポットの半径であり、図3の中央および右の2つの記録スポットMのように、記録光RBと光情報記録媒体10を互いに相対的に移動させた結果細長い形状となった場合には、記録スポットMの幅の半分として測定することができる。
図8(a)に示すように、基板11の上にサーボ信号層12を設けたワークに対し、中間層15の材料をスピンコートにより塗布し、紫外線を照射することで、中間層15を硬化させる。これにより、硬化後の中間層15の表面が、後に記録層14が形成される記録層形成面15Aとなる。
例えば、前記実施形態においては、記録層14は、記録光の照射により屈折率が小さくなるものを例示したが、記録光の照射により屈折率が大きくなるような記録材料を用いてもよい。この場合には、図10に示すように、記録スポットMが読出光OBを集めるように作用するので、記録部分において未記録部分よりも高い反射率で読出光OBを反射し、記録部分と未記録部分の反射光強度の変調が発生する。もっとも、変調度を高くして再生出力において高いS/N比を得るためには、記録層14においては、前記した実施形態のように、記録光の照射により屈折率が小さくなる記録材料を用いるのが望ましい。
