ABSTRACT:
A data storage apparatus includes a first lever body having a piezoelectric driving section, and a second lever body which is disposed to separate from and to be perpendicular to the first lever body, and has a piezoelectric driving section. A recording medium is formed on a portion of the second lever body, and records desired data. A plurality of probes are disposed on a portion of the first lever body to oppose the recording medium at a predetermined interval, and detect a change in state at predetermined positions on the recording medium as a change in tunnel current or a change in three-dimensional pattern. A voltage applying circuit alternately applies predetermined voltages to the piezoelectric driving sections of the first and second lever bodies to separately drive the plurality of probes in different directions, thereby three-dimensionally scanning the recording medium.
