ABSTRACT:
An magneto-optical disk apparatus has a magnetic head assembly a magnetic head slider loading mechanism. The magnetic head assembly has a magnetic head slider and a support arm for supporting the magnetic head slider. The magnetic head slider loading mechanism is fixed to a first yoke member 25 at the base of the support arm, to a generally U-shaped second yoke member fixed to a head carriage, and to a first towering part of the second yoke member. The magnetic head slider loading mechanism has a blade spring which has the first yoke member 25 fixed to the end of the blade spring, a coil provided in the first towering part, and a permanent magnet piece fixed to a second towering part. The magnetic force generated by the energization of the coil and the magnetic force of the permanent magnet piece causes the first yoke member to be magnetically attracted and attached to the second towering part so that the magnetic head slider is loaded above the magneto-optical disk.
