Abstract
An information recording and reproducing apparatus of the present invention, in which a tunnel current is utilized for recording information to a recording surface of a recording medium and/or for reproducing information from the recording surface, includes a slider which is arranged on the recording surface and floats above the recording surface by an air flow caused by movement of the recording medium. The slider includes a body having a first surface positioned opposite to the recording surface, a second surface parallel to the first surface, and a third surface oblique to the first and second surfaces. The slider further includes a cantilever having a projecting portion projecting from the body so as to be substantially parallel to the recording surface and a tip for detecting the tunnel current formed on a surface of the projecting portion on the side of the recording surface.
