超高密度探针存储技术的研究进展

Advances on Research of Ultra High Density Probe Storage

扫描探针显微镜(SPM)超高密度信息存储技术是近年来信息技术领域的新热点,并极有可能成为未来存储领域的主导技术 主要根据探针与样品表面的作用方式,分析了探针存储的机械学、电学、磁学、光学和化学作用原理,总结了用SPM实现信息存储的机械、电学、化学、磁学、近场光学、原子操纵等存储机理,提出实现超高密度信息存储必须从最基本的存储机理入手。

Ultrahigh densitiy data storage based on scanning probe microscope is the new focus of information technique in recent years and probably the dominant alternative in data storage in the future. In the paper, according to the performance of the probe and sample, theories of probe storage on mechanics, electronics, magnetics, optics, and chemistry are analyzed. Probe storage mechanisms, including thermomechanical storage, electric induced storage, chemical reaction storage, magnet storage, and scanning nearfield optics storage, and atom manipulation are introduced thereupon. Research on the basic modulation techniques of probe storage and the storage media is critical to realize ultrahigh density storage.
