Abstract

A near-field optical recording technique using a solid immersion lens (SIL) and a red semiconductor laser light source ((lambda) equals 650 nm) has been applied to the phase change optical recording. We have recorded and erased amorphous marks of 300 nm in diameter using a hemisphere SIL (n equals 1.84, designed effective NA equals 1.1).
