Abstract
In this thesis, we analyzed super resolution near-field structure(Super-RENS) with AgOx as mask layer. AgOx will be decomposed to Ag particles with various sizes under higher temperature on the center of laser spot. According to the observation and estimation from the reference, we propose a simple model of Super-RENS. From the finite difference time domain(FDTD) simulation, we proved that it would be better RF signal than DVD’s under smaller recording mark size.
According to the diffraction theory used in DVD system, we propose a new theory to analyze the RF signal and tracking error signal of Super-RENS disk. Then we use simulate the tracking error signal under beam aberration. Finally we use FDTD method to simulate the tracking error signal at defocus.
