SPMを用いた超高密度記録の現状と将来

抄録

Potential of scanning probe microscope (SPM)-based storage technique for ultrahigh density recording is presented. The SPM-based storage proposed here, STM (scanning tunneling microscope)-, AFM (atomic force microscope)-, MFM (magnetic force microscope)-, and SNOM (scanning near-field optical microscope)-based storages are described on areal density. The experimental results provide that contact type AFM-based storage is the most potential storage method for ultrahigh recording density and for high readout speed. It has the potential to achieve an ultrahigh density recording with a density of higher than 1Tb/in² and a readout of faster than 1Mb/s.
