Abstract
If a large external impact is applied to a magnetic disc apparatus, a slider jumps from a disc surface and rotates. When the slider jumps and rotates, its edges re-contact the disc surface to damage this surface. To reduce the rotation angle of the slider to control its position if an impact is effected, the present invention provides a roof on a load arm to reduce the contact angle at which the slider contacts the disc surface in order to relax the impact upon a contact.
Claims6
A magnetic-head supporting mechanism comprising a slider including a magnetic head that writes and reproduces data to and from a magnetic disc and that has a floating surface floating above the surface of said magnetic disc;
- a mounting portion on which said slider is mounted;
- a horizontal frame connected to one end of said mounting portion;
- two flexible finger portions extending from the respective ends of said horizontal frame to the respective sides of said mounting portion;
- a joint portion connected to other ends of said flexible finger portions and joined with one end of a beam portion;
- a spring portion having one end connected to the other end of said beam portion;
- and an arm mounting portion connected to the other end of the spring portion, wherein:
- said slider and said beam portion are joined together by using an elastic member having at least one loop-like flexed portion arranged in a region of a gap between facing sides of said mounting portion and said beam portion and which is not very rigid and has a high tensile strength in order to provide predetermined flex.
