ABSTRACT:
A magnetic head device in which, if a rotated magneto-optical disc is subjected to surface deviations, a slide contact member can have a sliding contact with the magneto-optical disc at a constant slide contact posture at all times to make possible correct application of an external magnetic field. To this end, first resilient flexible portions (7, 7) and second resilient flexible portions (8, 8) have spring constants set so that a point for which an angular change of the first resilient flexible portions (7, 7) is always equal to an angular change of the second resilient flexible portions (8, 8) that is an equilibrium point, will be present within the extent of a slide contact area.
