Abstract: 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.

Abstract: In a reproducing operation, scanning information is detected while scanning an information string with a probe such that a density of the scan lines is higher than a density of the recorded information, and a logical-sum signal of the plurality of scanning information is used as a reproduced signal. It is thereby possible to prevent deterioration during information processing of the S/N ratio and the like produced due to a positional error of a recording-medium control mechanism caused by various factors.

Abstract: 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 or 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.

Abstract: An information processing apparatus for accumulating image information consisting of n pixels and effecting the processing of output of the information is provided with a plurality of memory devices, a distributing device and an output control device. The information is stored in the plurality of memory devices. By the distributing device, the image information consisting of the n pixels are divided into m pixel unit basis (n > m), and the information consisting of the m pixels into a p (m > p) pixel unit basis, and the plurality of information each consisting of the p pixels are distributed to the plurality of memory devices. Upon the output of the image information, the information stored in the plurality of memory devices are selectively outputted by the output control device.

Abstract: 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.

Abstract: An image photosensor includes a photosensor unit, a charge storage unit, and a switch unit, all of them formed on a single-crystal semiconductor film grown from a single nucleus such that crystal formation is performed on a substrate having a free surface including a non-nucleus formation surface and a nucleus formation surface adjacent thereto. The non-nucleus formation surface has a low nucleation density. The nucleus formation surface has a sufficiently small area to allow growth of only the single nucleus and has a higher nucleation denstiy than that of the non-nucleus formation surface.
