“…However, the low optical transmission and some problems in controlling the near-field distance between the probe tip and the sample surface results in difficulties in its application to the high-speed rotation optical disk system. 7 The solid immersion lens near-field method can obtain a subwavelength spot and produce nanometric information marks. It can also maintain a higher optical transmission compared with the near-field probe technique.…”

Nano-optical information storage is very important in meeting information technology requirements. However, obtaining nanometric optical information recording marks by the traditional optical method is difficult due to diffraction limit restrictions. In the current work, the nonlinear saturable absorption effect is used to generate a subwavelength optical spot and to induce nano-optical information recording and readout. Experimental results indicate that information marks below 100 nm are successfully recorded and read out by a high-density digital versatile disk dynamic testing system with a laser wavelength of 405 nm and a numerical aperture of 0.65. The minimum marks of 60 nm are realized, which is only about 1/12 of the diffraction-limited theoretical focusing spot. This physical scheme is very useful in promoting the development of optical information storage in the nanoscale field.

This paper describes our high‐density near‐field optical recording using bent cantilever fiber probes installed in an atomic force microscope. We conducted a near‐field reading of nano‐scale hole patterns with a 100 nm spatial resolution and a 25 µm/s scan speed; this implies a capability of a data reading density of 60 Gb/in2 with a 0.25 kbps data transfer rate. In addition, we investigated re‐writable near‐field recording on photochromic diarylethene films. We successfully recorded erasable memory bits having a minimum width of 600 nm in a writing time as short as 30 ms. We found that using a cantilever probe simplifies the setup and operation of the near‐field optical recording system and may offer multifunctional recording capabilities.
