Paper Abstract

We present a study on the feasibility of extending our current experimental cover-incident near-field recording system to a 4-layer system promising 500 GB storage capacity on a single sided 12 cm disc. We calculated the electromagnetic field inside a 4-layer disc of which the design was optimized to have a minimum in the irradiance near recording layers other than the one that the light is focused on. Furthermore an objective lens and compensation device were designed to accommodate writing and reading from all four layers.
