Abstract: Apparatus for detecting data in a sensor signal generated by a read sensor in a local probe data storage device comprises a differentiation for subtracting a value of the sensor signal from the succeeding value of the sensor signal to generate a ternary difference signal; and a convertor connected to the differentiator for converting the difference signal into a binary output signal indicative of the detected data. A local probe data storage device comprising such apparatus is also described.

Abstract: In accordance with the present invention, there is provided an apparatus comprising a tape having an information layer on which information is storable in the form of perturbations, an array of probes that in function faces the tape such that the probes scan the surface of the tape, means for selectively forming the perturbations via the probes, means for detecting the presence of the perturbations via the probes, and drive means for moving the tape relative to the array of probes. The apparatus allows to store high data capacities at a small form factor.
