Ultrahigh-Density StorageMedia for Near-Field Optical Recording

Two types of recording media possessing nano-dot structures were investigated. The media were prepared by an artificially assisted (or aligned) self-assembling (AASA) method, which includes simple nano-patterning using a nano-imprint and fine nano-patterning using self-assembling organic molecules. The AASA method were successfully applied to fabricate magnetic patterned media for opto-magnetic hybrid recordings and fluorescent organic dye media for near-field optical recording. H. Hieda ( ) K.
