Abstract: The present invention concerns a storage device comprising a local probe array (72) and a storage medium (70) with an array of storage fields (71). The local probe array (72) is situated opposite to the storage medium (70) such that each local probes (73) of the local probe array can be scanned over the corresponding storage field (71). The storage device further comprises circuit for distinguishing between information to be erased from a first section of the storage medium and information in this section which is not to be erased, circuit for selectively copying the information which is not to be erased into a memory, preferably another section of said medium, and circuit for erasing the whole first section.

Abstract: An investigation and/or manipulation device for a sample which is located in a container fluid includes an investigation and/or manipulation tool which is mounted at a first of a cantilever and which during investigation and/or manipulation of the sample immerses into the container fluid. The opposite side of the cantilever is at least partly not immersed into the container fluid during investigation.

Abstract: A cantilever for scanning probe microscopy and other force or deflection measurements is described. The cantilever includes at least one one integrated strain sensing element within a constriction section (62) . The cantilever is improved over known cantilevers by reducing the longitudinal extension of the constriction, such that its contribution to the total deflection of the cantilever is reduced. The design of the cantilever is further improved by applying a beam (63) with an essentially triangular cross section in either a vertical or a horizontal plane or both.
