ABSTRACT:
A probe-based storage device comprises a storage surface for storing data represented by deformations in the surface. A probe faces the surface and includes a resonant circuit having a reactance dependent on deflection of the probe relative to the surface. A scanner is provided for scanning the probe across the surface such that the probe follows said deformations. A detector reads data stored on the surface by detecting variation of the resonant frequency of said circuit.
