    • A magnetic head apparatus for a magneto-optical recording medium recording and/or reproducing apparatus includes a head body and an arm-shaped support mechanism. The head body includes a magnetic head unit for generating a perpendicular magnetic field, and a contact-slide portion to which the magnetic head unit is secured and which is slid along the magneto-optical recording medium in contact with the surface of the magneto-optical recording medium. The arm support mechanism to which the head body is secured is movable in such a direction that the magnetic head unit is contacted with or away from the magneto-optical recording medium. The arm-shaped support mechanism has an arm portion, a fixed portion and first and second elastic displacing portions. The head body is secured to one end side of the arm portion through the first elastic displacing portion. The fixed portion has one end secured to the fixed member and the other end portion has one end secured to the fixed member and the other end which is linked to the other end of the arm portion through the second elastic displacing portion. The arm-shaped support mechanism is disposed so as to sandwich the central axial line of the support mechanism, and it comprises a pair of plate-shaped elastic members constituting the first and second elastic displacing portions, and a resin portion which is provided at both sides of at least one of the elastic members and forms the arm portion and the fixed portion.
    • 用于磁光记录介质记录和/或再现装置的磁头装置包括头本体和臂状支撑机构。 头体包括用于产生垂直磁场的磁头单元和固定磁头单元的接触滑动部分,并且沿着磁光记录介质滑动,与磁光表面接触 记录介质。 头部固定到其上的臂支撑机构可以沿磁头单元与磁光记录介质接触或远离的方向移动。 臂状支撑机构具有臂部,固定部以及第一和第二弹性位移部。 头部主体经由第一弹性位移部固定在臂部的一端侧。 固定部的一端固定在固定部件上,另一端部具有固定于固定部件的一端,另一端部通过第二弹性位移部与臂部的另一端连结。 臂状支撑机构设置成夹持支撑机构的中心轴线,并且其包括构成第一和第二弹性位移部分的一对板状弹性构件和设置在两者上的树脂部分 至少一个弹性构件的侧面并形成臂部和固定部。
