Probe and information recording/reproduction apparatus using the same

摘要

Probe including a cantilever having a movable end and formed from an elastic body, an electroconductive sensing needle arranged at the movable end of the cantilever, and a field effect transistor arranged at the movable end of the cantilever and having a gate electrode electronically connected to the electroconductive sensing needle. The probe may further comprise another field effect transistor formed on the cantilever and having its drain electrically connected to the sensing needle. The probe may be used in an information recording/reproduction apparatus.
