Abstract
A read/write arrangement for a contact probe storage arrangement or the like, has a cantilever disposed with a medium which is movable relative to the cantilever; a device associated with one of the cantilever and the medium which is configured to be responsive to changes in electrical field between the medium and the cantilever caused by a change in distance between the medium and the cantilever; a heater disposed on the cantilever for heating the medium and for inducing localized topographical changes which represent bits of data; and a circuit which electrically interconnects both of the device and the heater.
Claims12
A read/write arrangement comprising:
- a cantilever disposed with a medium that is supported on an electrically conductive substrate and that is movable relative to the cantilever;
- a device included in the cantilever and being responsive to changes in an electrical field that is generated between the electrically conductive substrate of the medium and the cantilever caused by a change in distance between the medium and the cantilever;
- a heater disposed on the cantilever for heating the medium and for inducing localized topographical changes which represent bits of data;
- and
- a circuit that electrically interconnects both of the device and the heater and that responds to changes in current through the device caused by changes in the electrical field.
