ABSTRACT:
The invention provides a simply constructed magnetic disk device with a head lift system that can improve reliability and reduce costs. A head arm is integrated with a rigid base section, a spring, and a rigid tip. A magnetic head is fixed to the tip of a head holder. A contact section of a lateral bar form is formed in the tip, which is normally kept away from the under surface of the head holder so that it will not make contact. When the tip is lifted, however, the contact section contacts the under surface of the head holder and lifts it together. To contact with the pin fixed on the tip of the tip, a cam is engraved and formed on part of a cover plate. The cam consists of a plane section, an inclined section which ascends to the left in the figure, and a semi-circular concave section into which the pin can be fitted, thus forming a contour face. The pin moves depending on the contour to a predetermined position when the head arm turns toward the center, and the magnetic head departs from the disk during a head lifting operation.
