摘要:
An information processing apparatus utilizing a scanning tunnel microscope includes a probe, a detector for detecting the distance between the probe and an object opposed thereto, based on a physical interaction working between the probe and the object, an electrostatic actuator for displacing the probe, for adjusting the distance between the probe and the object. The electrostatic actuator includes mutually opposed two electrodes: A controller is provided for controlling the amount of charge to be accumulated between the electrodes, so as to maintain a desired distance between the probe and the object, based on the result of detection by the detector.

A digital television receiver having an STM memory is provided with a receiving unit to receive a broadcasting signal, a producing circuit to produce an image signal and a voice signal from the received broadcasting signal, a memory which is used to record the image signal and the voice signal and has a plurality of probe electrodes and a recording medium arranged so as to face the probe electrodes, a display for converting the image signal outputted from the memory into the video image, and a speaker for converting the voice signal outputted from the memory into the voice sound. The memory further has a voltage applying circuit for applying a voltage to the portion between each probe electrode and the recording medium. The image signal and the voice signal are digital signals.
摘要:
There is disclosed an information recording/reproducing apparatus utilizing a probe electrode and a recording medium, based on the principle of scanning tunnel microscope. When a track groove on the recording medium is detected, the distance control between the probe electrode and the recording medium is suspended. Consequently, the tip of the probe electrode does not enter the track groove, and is prevented from collision with the recording medium. The scanning speed of the probe electrode can, therefore, be increased without the danger of such collision.

A recording and reproducing method writes information in the form of bits by the physical interaction between a probe and a recording medium opposed to the probe. The method includes a recording step of recording information by shifting a forming position of each bit by a predetermined shift amount in a horizontal direction of the recording medium in accordance with information, and a reproducing step of reproducing the information, based on the shift amount of each recorded bit in the horizontal direction of the recording medium. A recording and reproducing apparatus is so constructed as to perform the steps.

The specification also discloses a method of reproducing information recorded on a recording medium by such information recording method. The specification further discloses an apparatus for carrying out the information recording method, and an apparatus for carrying out the information reproducing method.
摘要:
An apparatus capable of detecting a displacement of a probe from a track of a recording medium caused by track fluctuations and vibrations at a recording/reproducing period. For example, a probe is maintained to vibrate at a frequency and in the direction perpendicular to a data train at a amplitude smaller than the width of the data train. In this case, the amplitude of a reproduced signal of the data train changes with the displacement between the probe and the data train. An envelope signal of the reproduced signal is phase detected using as a reference signal the vibration waveform (standard signal) at frequency f.sub.o of the probe, to obtain a signal proportional to the displacement from the data train. Using this signal, it becomes possible to feedback control the probe so as to make it trace the data train.

Information recording/reproducing apparatus and method by use of probe electrodes are disclosed. In this method, information to be recorded on a recording medium is encoded. The encoded information is distributed to a plurality of probe electrodes. The plurality of probe electrodes are driven on the basis of the distributed information so as to record the information on the recording medium. In reproduction, the information recorded on the recording medium is read out from the recording medium by use of the plurality of probe electrodes. The information read out from the recording medium is stored by use of the plurality of probe electrodes. The stored information is decoded to reproduce the information recorded on the recording medium. The encoding is performed by changing the information to be recorded to information added with an error correction code.

An encoder or an information reading device detects a scale with a probe that is vibrated at a predetermined frequency and amplitude in a predetermined direction. The angular positional relationship between the direction of probe vibration and the scale is detected according to frequency spectrum information of a detection signal obtained by detecting the scale with the vibrating probe.

摘要:
In an apparatus including a recording medium on which a multiplicity of information bit lines are formed and a probe facing the recording medium, the displacement between the center of the information bit line and the locus of the probe is detected at the time of relatively moving the probe along the information bit line. Tracking is performed in such a manner that the probe scans the center of the information bit line in accordance with the detection results.
