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： A near-field optical head capable of rapid recording and/or reproducing of the information is provided. The near-field optical head condenses the light from the light source and irradiates the light on the minute opening 1. Then, by means of detecting the reflected light from the light condensing mark 501 provided on the circumference of the minute opening 1, the relative position between the light condensing point condensed by the lens and the light condensing mark 501 is detected so that the light condensing point is controlled to follow the light condensing mark 501. Thus, intensive and constant near-field light can be generated in the minute opening 1 and a signal having high S/N can be obtained even by a rapid scanning of the minute opening 1 over the recording medium so that rapid recording and/or reproducing of the information is made possible.
