    摘要: 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.

    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 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.

    摘要: An apparatus and method for moving a first object relative to a second object is provided. One of the first and second objects is moved and thereby guided by a tracking device. The tracking device uses a pattern on the first object and/or second object and a releasable clamping device for holding the first and second object in contact. The first and second object can then be releasably clamped such that the patterns match and the clamping device holds the first and second object in a position defined by the pattern. This invention is particularly well suited for nanomechanical or micromechanical applications.

    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.

    摘要: A system to improve the uniformness of patterns for LSI circuits or masks generated in an electron beam lithographic system uses a backscatter indicator signal to vary a control signal for the beam stepping rate proportional to the variations in the amount of backscattered electrons. This avoids non-uniformity such as line width variations which otherwise occur when the pattern to be generated covers border lines between two different substrate or base layer materials. Range setting circuitry is provided for adjusting, during an initial prescan of a sample of two materials having an extreme difference in their backscatter characteristic, the offset and the gain for the backscatter detector. During subsequent exposure of a wafer, the backscatter indicator signal and thus the stepping rate control signal variations remain within preselected limits.

    摘要: An arrangement for separating disturbing ambient light from an optical data signal, comprising an interference filter (1), the passband of which matches the wavelength of the optical data signal, and further comprising two photodiodes which are so arranged that one photodiode receives the light (I.sub.S, I.sub.AT) transmitted through the interference filter, and that the other receives the reflected light (I.sub.AR). Adjusting means, e.g., in the form of a settable aperture (4) or an additional simple filter (5) are provided for adjusting the transmitted and reflected portions of the ambient light to each other. Output signal (S1, S2) of both photodiodes are subtracted from each other in compensation circuitry (6). This results in compensation of the ambient light components so that at the output a signal (SR) is available which depends only on the actual data signal (I.sub.S).
