摘要： A fine positioning apparatus is provided which comprises inductive actuators (2, 3). A positioning accuracy of well below 1 nm is achieved compared to 1 νm provided by known inductive actuators. In preferred embodiments, the motion of the magnetic actuator is dampened or decreased by mechanical means (5, 6, 35), thus increasing the amount of current necessary to move the actuator. The fine positioner can be used in the field of scanning probe microscopy.

摘要： A data storage device comprises a storage medium, at least one probe designed for creating indentation marks in the storage medium, a control unit designed for creating a control parameter (CTRL) acting on the probe resulting in the creation of one indentation mark. The control unit is further designed for modifying the control parameter (CTRL), if at least a given number of consecutive indentation marks with a given minimum distance between each other should be created. According to the method the control parameter (CTRL) is modified if at least a given number of consecutive marks with a given minimum distance between each other should be created.

摘要： 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 (10) of probes (11) that in function faces the tape (2) 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 (20, 25, 40, 42) for moving the tape relative to the array of probes. The apparatus allows to store high data capacities at a small form factor.

摘要： The present invention concerns a cantilever arrangement for scanning a surface (16). This arrangement comprises a first cantilever (11) having a first probe (14) and a second cantilever (13) having a second probe (15). Both cantilevers (11, 13) are mechanically coupled such that the second cantilever (13) follows the movement of the first cantilever (11), i.e. the deflection of the first cantilever (11) defines the deflection of the second cantilever (13).
