我们采用超波长孔径光纤探头进行相变记录/读出。光纤探头虽然具有超波长孔径，但光斑尺寸仅为150 nm （< λ/5）。采用沉积的SiO2/AgInTe2/玻璃基板作为记录介质。采用脉冲宽度为2 μs （λ=850 nm）的激光二极管进行记录。通过扫描探针读取，我们获得了宽度为250 nm的记录点的分辨率图像。
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 (< λ/5). An as-deposited SiO2/AgInTe2/glass substrate was used as a recording medium. For recording, a laser diode with a pulsewidth of 2 μs (λ=850 nm) was used. By scanning the probe for reading, we obtained resolved images of the recorded dot with a width of 250 nm.
