Is composed of a single conductor spring member 32, in other words, the mechanical support (metal spring) member 20 and the electrical connection (conductive flexible) member 22 in the above-described conventional mechanism 18 (FIG. 2). Since both functions of (1) and (2) are constituted by the single conductor spring member 32, compared with the conventional mechanism 18, first of all, the number of parts is reduced and the assembling is easy and the man-hours are small. It is clear that the cost will be reduced. Moreover, it is easily understood that the contact pressure p of the magnetic field modulation head 10 with respect to the magneto-optical disk 12 (head-to-disk pressure) p is well stabilized because this pressure is regulated by the single member 32. It is about to be done. Needless to say, the vibration system of the mechanism 30 is improved.
