| Abstract: | Theoretical and experimental research results obtained in signal detection in an optical data storage system with a solid immersion lens are introduced. This is very important for SIL(Solid Immersion Lens) to be as an applicable technique in high density optical data storage. 3 D diffraction theory for solving some mechanism problems in SIL is introduced. Some factors that influence the readout signals are discussed in details, such as gap width, disk structure and polarization. Some new techniques for signal detection in a SIL based optical data storage system and some important experimental results are presented. |
