摘要： The purpose of the invention is to fabricate a near field optical head capable of recording and reading high density information at high speed with excellent mass production. In the invention, stoppers having almost the same height as that of a tip of conical or pyramidal shape are disposed around the tip, a part of a pressing body covering the tip and the stoppers is displaced by an external force, a part of the pressing body having displaced is allowed to come into contact with an opaque film near the point of the tip and thereby an aperture is formed. According to a fabricating method of the invention, multiple apertures can be formed in a block. Thus, the near field optical head is excellent in mass production and the formed aperture has a structure of high optical efficiency and high resolution. Therefore, the near field optical head capable of performing recording/reading in high density and at high speed can be fabricated in excellent mass production.

摘要： In a combined scanning near field optical microscope (Nsom) and atomic force microscope (AFM), an optical fibre probe (1) which has a minute opening on the top of a sharpened tip is brought close to a sample (2), and the probe is moved by a piezo actuator (15) along x- and y-axis directions so that a minute spot beam emanating from the minute opening can scan over the sample. For circular polarisation modulation to be incorporated in the process, a beam is given an optical delay, before it is incident on the optical fibre probe (1), changing at a frequency of p (Hz) by means of a piezo-optical modulator (10). A minute spot beam emanating from the minute opening passes through the sample (2) to be received after passage through the sample (2) to be received after passage through an analyser (5) by a light receiving element (7). The output from the light receiving element (7) is fed to a lock-in amplifier, p- and 2p-components are separated through lock-in rectification, and they are rendered into images by a controller (16). It is used for measuring the distribution of magneto-optical effects.
