AFM-based data storage and microscopy

摘要: Read/write components for AFM-based data storage devices are provided. In particular embodiments, a read/write component comprises lever means and support structure, the being connected to structure substantially pivotal movement. The provides first second current paths between pair of electrical supply lines on via which can be in use power operable write mode read mode. A write-mode heater is provided path, tip heater. read-mode path. Decoupling arranged inhibit flow path when operated component, with separate heaters, thus addressed both modes single lines. Other embodiments provide employing thermal decoupling mechanism, where read-sensing performed by proximity sensing arrangement structure. Sensing apparatus atomic force microscopes also movement detected similar arrangements.
