摘要： PROBLEM TO BE SOLVED: To provide a magneto-optical recording device in which recording speed of an information signal can be improved by reducing the area of a magnetic field generating plane of a magnetic head.
SOLUTION: A suspension 15 supporting a magnetic head 10 is constituted of a member different from that for a gimbal 14. The characteristics of the gimbal 14 can be consequently made compatible with that of the suspension 15 although they are different from each other, namely, the characteristics of the gimbal 14 is that the gimbal 14 minimizes power loss when supplying current while sufficiently and elastically holding the magnetic head 10, and the characteristics of the suspension 15 is that the suspension 15 suppresses the displacement and the rotational displacement of the magnetic head caused by the vibrations and impacts applied from the outside. Thus, the displacement of the magnetic head caused by the vibrations and impacts applied from the outside or the horizontal displacement of the magnetic head caused by the vertical displacement of the recording medium 4 can be reduced, so that a light spot can be formed in a magnetic field apply region even if a core size of the magnetic head 10 is made small, consequently, the inductance of the magnetic head is reduced, and the recording speed can be improved.

摘要： PROBLEM TO BE SOLVED: To improve frequency characteristics for an optical pickup by strengthening a rigidity of a rising piece without making a metal plate thicker when the rising piece for attaching a magnet is formed by bending the metal plate for an actuator of the optical pickup.
SOLUTION: Rising pieces 23, 23 are molded by bending on a base component 2 for holding a lens holder 1 with an objective lens 13 to be displaced toward both a focusing direction and a tracking direction. Strength for the base component 2 is enhanced by broadening width to other positions for a molded by bending part 32 for a foot 31 for the rising pieces 23, 23. It is desirable for a side view shape for the rising piece 23 to be made a trapezoid.
