摘要:
The present invention relates to computer storage systems which have a tip (24) directed close or in contact to the storage medium (10) by which bit-writing and bit-reading is enforced. It is proposed to use a magnetizable storage medium (10), expose it to an artificial, external magnetic field H coupled externally to the storage medium, and—during bit writing—to concurrently apply heat very locally in bit size dimension in order to let the external magnetic field become locally larger than the (temperature-dependent) coercive field at the location (32) where heat is applied. Further, a two-dimensional array of cantilever tips (24) is advantageously used in an inventional storage system each of which tips serves as a heat source when it is activated by a current flowing through a resistive path within said tip (24) and producing the necessary temperature at the small storage medium location (32) where the bit writing is intended in order to approach the Curie temperature or the compensation temperature of the magnetic material.

A method for writing data to and/or reading data from locations on a surface via a tip comprises moving the tip between the locations on the surface. At each location, energy is selectively applied to the surface via the tip and the tip and the surface are selectively forced together in synchronization with the application of energy.

An optical device comprises a substrate having a plane surface. An optical path is disposed on the substrate and extends in a plane parallel to the surface of the substrate. A recess intercepts the optical path. An optical element is provided for modifying light incident thereon. The optical element is moveable within the recess between a first position in which the optical element is located in the path and a second position in which optical element is remote from the path. A cantilever suspends the optical element for movement within the recess between the second and first positions in a direction normal to the surface of the substrate.

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.

An investigation and/or manipulation tool for a sample which is locally deformed when subjected to a local heat treatment includes a power supply for heating a tip of the tool wherein the tool has a structure such that the power supplied to the tip heats substantially only the tip of the tool and includes a region of relatively high heat conductivity that provides fast cooling of the tip when power is not supplied to the tip.
摘要:
The present invention discloses a method of forming ultrasmall (nano) structures in a thin film provided on a substrate by means of a tip which is movable relative to the surface of the thin film. According to principles of the invention, the penetration depth of the tip is limited, thereby avoiding wear of the tip. Furthermore, an apparatus for carrying out the method is disclosed.

The present invention concerns a cantilever arrangement for scanning a surface. This arrangement comprises a first cantilever having a first probe and a second cantilever having a second probe. Both cantilevers are mechanically coupled such that the second cantilever follows the movement of the first cantilever, i.e. the deflection of the first cantilever defines the deflection of the second cantilever.

A fine-positioning apparatus for a scanning probe microscope includes magnetic solenoid actuators for each of the x, y and z scanning axes of the microscope. The sample is mounted on the coil of one of the actuators for movement of the sample in the z direction while the tunnelling probe is attached to two other solenoid actuators for movement of the probe in the x and y directions.
