An information recording and reproducing apparatus is disclosed. The apparatus has a signal processing unit for signal processing for information recording on and reproduction from an information recording medium and a probe which is positioned opposed to the information recording medium. The signal processing unit is adapted to effect information recording on and reproduction from the information recording medium through the longitudinal end of the probe. The probe includes a supporting member and a rod-shaped projection of which the end is positioned opposed to the medium. The rod-shaped projection protrudes from a partial area of the supporting member. By the apparatus, it is possible to precisely and accurately record and reproduce information regardless of the surface state of the medium.
