・Pd原子の比率:10〜60原子%、
・Ag原子の比率:5〜45原子%、および
・Pd原子とAg原子の合計量:75原子%以下

・Pd原子の比率:10〜60原子%、
・Ag原子の比率:5〜45原子%、および
・Pd原子とAg原子の合計量:75原子%以下
を満たすものを用いる。
ディスク基板として、ポリカーボネート基板(厚さ:1.1mm、直径:120mm、トラックピッチ:0.32μm、溝深さ:25nm)を用い、該基板上に、DCマグネトロンスパッタリング法により、酸化In、酸化Pdおよび酸化Agからなる種々の記録層を形成した。記録層の膜厚は40nmとした。上記記録層は、純In金属ターゲット、純Pd金属ターゲット、および純Ag金属ターゲットの3つのターゲット(表1のNo.5、8は、このうちの2つのターゲット)の同時放電による多元スパッタリングを行って形成した。
作製した光ディスクについて下記の通り評価した。即ち、光ディスク評価装置(パルステック工業社製「ODU−1000」)を用い、記録レーザー中心波長は405nmとし、NA(開口数):0.85のレンズを用いた。下記に示す反射率は、上記装置を用い、レーザーをトラック上に照射し、光ディスクにおける未記録部分のレーザー光の戻り光強度から求めた。
変調度(反射率の変化率)=(未記録部分の反射率−記録部分の反射率)/(未記録部分の反射率) …(1)
これらの結果を表1に併記する。
