摘要:
An information processing apparatus effects at least one of recording, reproduction and erasure of information on a recording medium having a track groove by use of a probe electrode. Relative movement between the probe electrode and the recording medium is effected by the moving mechanism. A predetermined driving signal is inputted to the moving mechanism so that a predetermined movement of the probe electrode to the groove track is effected. The physical phenomenon caused between the probe electrode and the recording medium is detected, so that the track groove is detected and a correction value for correcting the movement of the probe electrode from the driving signal on the basis of the timing of the detection. The moving mechanism is controlled on the basis of the driving signal and the correction value.

An information processing apparatus for effecting recording of information on and/or reproduction of information from a recording medium is provided with a probe electrode, a cantilever piezo-electric member, a controller and a detector. The probe electrode is relatively displaced to the recording medium by the cantilever piezo-electric member. The controller applies a control signal to the cantilever piezo-electric member to control the cantilever piezo-electric member. The detector detects a minute signal obtained on the tunnel effect caused between the probe electrode and the recording medium. A switch element is further provided on the apparatus so as to electrically disconnect between the cantilever piezo-electric member and the controller during the minute signal being detected by the detector.

In order to provide high-quality image display by correcting and uniformizing the nonuniformity of electron emission characteristics, a predetermined arithmetic operation is performed by using correction values for correcting the nonuniformities of luminance caused by the electron emission devices when a predetermined voltage is applied thereto, thereby calculating correction values when the voltage having a plurality of voltage amplitude values is applied thereto. Corrected image data are calculated on the basis of the calculated correction values, and a drive signal is outputted to drive the electron emission devices on the basis of the corrected image data.

The present application discloses a characteristic adjusting method of executing a step of changing the characteristics of display devices in an image display apparatus. In particular, the present invention discloses a configuration in which target values for changes in characteristics are obtained by reducing the high-frequency components of the spatial distribution of the characteristics of the display devices.
摘要:
An apparatus for and a method of moving a probe for causing a physical phenomenon to occur between it and a predetermined object and moving the probe and the object relative to each other to make the probe approach the object. At least one of the probe and the object is driven in a predetermined direction to displace one of the probe and the object in the predetermined direction relative to the other. A physical phenomenon occurring between the probe and the object is detected. At least one of the probe and the object is driven so as to bring the probe and the object close to each other. The driving for the approach of the probe to the object is controlled on the basis of the result of the detection of the physical phenomenon during the driving in the predetermined direction. The specification also discloses an information detection and/or input apparatus using such apparatus and method.
摘要:
An information reproducing apparatus includes a recording medium and a reproducing probe, and reproduces information from a signal between the recording medium and the probe. The apparatus further includes a unit for obtaining reproduced information from each of a plurality of data unit areas of the recording medium under different conditions. By obtaining a plurality of different kinds of information from scanning each recording region under the different conditions in a reproducing operation, it is possible to perform correction by discriminating a change in a tunnel current reflecting a recording bit from a tunnel current caused by projections and recesses of the surface and to remove a resulting error.
