Progress in Nano-Electro Optics III

Near-?eld optical recording is a promising way to realize a recording density 2 of over 1 Tb/in . When a TbFeCo recording medium was placed 10 nm from the ne- ?eld optical head, the size of the optical spot was 30 nm, which corresponds 2 to an areal recording density of approximately 1 Tb/in .
