Abstract
In a magnetic disk supporting device of a type that the longitudinal direction of the supporting device extends in the tangential direction of the tracks of a magnetic disk, the direction of float rails on the slider of the magnetic head is the same as the longitudinal direction of the supporting device, and the slider is fixed to the lower surface of a central tongue portion constituting a part of the supporting device at a position that the front end of the slider does not overlap with a lateral frame as a part of the supporting device, whereby stable operation of the magnetic head can be obtained.
Claims3
A magnetic head supporting device of a type wherein the longitudinal direction of the supporting device extends in the tangential direction to the tracks of a magnetic disk, and which comprises:
- a supporter having a flexible spring portion and a rigid beam portion contiguous to said flexible spring portion;
- a flexible piece having a flexible flat portion extending substantially parallel to the longitudinal direction of said supporter, a pair of flexible outer frame portions extending from both edges of a free end of said flexible piece and parallel to the longitudinal direction of said supporter, a lateral frame portion connecting the free ends of said pair of flexible outer frame portions, and a central tongue portion formed of a substantially rectangular flexible plate which has one end fixed to the intermediate part of said lateral frame portion and the other end extending inside and substantially parallel to said pair of flexible outer frame portions to form a free end, said flexible piece having the other end fixed to said supporter;
- a loading projection attached to the upper surface of said central tongue portion or the lower surface of the terminal portion of said supporter to transmit a loading force at the terminal portion of said supporter to said central tongue portion;
- and
- a magnetic head with a slider attached to the lower surface of said central tongue portion, wherein the slider includes float rails and reading/writing elements and is placed in such a manner that the float rails extend in the same direction as the longitudinal direction of said supporter and the front end of the float rails of said slider does not overlap with said lateral frame portion.
