ABSTRACT:
An optical recording and reproducing system including a read/write head assembly including an objective lens for reading or writing information on an adjacent magneto-optical recording medium. A solid immersion lens is disposed between the objective lens and the recording medium with a surface closely spaced from the recording medium. The closely spaced surface is provided with a mask having an opening which defines the extent of evanescent fields coupled to the recording medium.
