Paper Abstract

Through the coupling of evanescent waves into the recording medium, the size ofthe marks that a SIL-based optical system is able to write and read is substantially reduced. This promises a significant increase in the storage density and data rate of optical storage devices. However, without properly controlling the flight height ofthe SIL above the spinning disk, the available optical energy for recording as well as the readout resolution are severely compromised. Here we present results of numerical simulations pertaining to evanescent coupling for magneto-optical (MO) and phase-change (PC) disks through a solid immersion lens.
