Abstract
We applied a super-wavelength apertured fiber probe to phase-change recording/readout. Though the fiber probe had a super-wavelength aperture, the spot size at the aperture was as small as 150 nm (< (lambda) /5). An as-deposited SiO2/AgInTe2/glass substrate was used as a recording medium. For recording, a laser diode with a pulsewidth of 2 microsecond(s) ((lambda) equals 850 nm) was used. By scanning the probe for reading, we obtained resolved images of the recorded dot with a width of 250 nm.
