中文摘要	recent theoretical and experimental results suggested that the silver superlens could be constructed through controlling silver thin film thickness and preparation conditions, and applied in subdiffraction-limited optical imaging and optical lithography. in this work, we report another significant application of silver superlens-ultrahigh density optical data storage. with the silver superlens the subdiffraction-limited pit arrays on an optical disk are dynamically read out and the carrier-to-noise ratio can reach 25 db for the thin film thickness of 46 nm. the readout laser power and readout velocity have little effect on the carrier-to-noise ratio. additionally, in our experiment the silver thin film thickness needs to be controlled in the range from 20 to 80 nm.
