Surface plasmon propagation properties for nano-sized metal aperture and nano-wire structures are studied based on the waveguide theory. It is verified that there are only TM0 and HE1 mode existing in both structures. For nano-wire structure, however, there is no cut-off radii for both TM0 and HE1 mode. On the contrast, there is a cut-off radius for nano-sized silver aperture structure, and even more, there are several characteristic radius coefficients a/lambda, - 0.32, 0.73. For each section, the EM wave may takes on different features, e.g.. totally-bounded features along the aperture interface for a/lambda > 0.73, or oscillation inside core or strong attenuation along z direction for 0.32 < a/lambda <0.73. HE1 mode of metal aperture doesn't show cutoff radius as well, but the wave-number along z direction monotonically increase with the radius coefficient a/lambda in contrast with existence of a characteristic radius coefficient a/lambda of 0.41 for nano-wire

Practical optics for a cover-layer incident dual-layer disc with an NA=1.45 hemispherical solid immersion lens are designed, using a spherical aberration compensating liquid crystal cell. A hybrid servo system, gap servo for NA >1 and focus servo for NA < 1, is proposed.

The paper presents an overview of techniques designed to increase data storage density by putting more than a single bit of information into a single pit. The current solution differs from previous suggestions in that we do not require an improved signal-to-noise ratio to achieve higher data storage density. Instead we use a hitherto unutilised feature of light: its polarisation. Although the research is still very much ongoing the paper reports on the progress so far and summarises future development directions

50GB BD-R media with Te-O-Pd recording material was estimated to have a life expectancy of over 500 years according to acceleration test under stressed conditions. This stable recording material will reduce the possibility to lose important data even in sever storage environment.
