摘要：

The possibility of SPM-based data storage is described regarding both its recording density and readout speed for ultrahigh density data storage. We consider their gap control to achieve high-speed readout, Suitable SPM-based storages are selected and their details are studied. as a result, scanning near-field optical microscope (SNOM)- and atomic force microscope (AFM)-based storages are expected to be candidates for future storage. SNOM-based storage is for 100 Gb in(-2). AFM-based storage is for 1 Tb in(-2). Using new force modulation AFM pit recording, an ultrahigh recording density of 1.2 Tb in(-2) and a readout speed of 1.25 Mb s(-1) are demonstrated.
