Magnetic head support device for magnetic disc recording device

摘要

When a slider slides on a recording medium and a frictional force acts on the slider, an unstable vibration resulting from falling forward of the slider and a local stress are prevented from being generated. An attitude of the slider is stabilized, and the slider is kept in a steady contact with a disc. A rotary support mechanism is constituted by successively connecting one deformable portion, one rigid portion and another deformable portion to an upstream side of another rigid portion with a slider attached thereto in a recording medium movement direction. The another deformable portion is bonded to a support arm. While a predetermined pressing load is given to the slider by a spring portion, an intersection of an extension of a virtual line connecting the one and another deformable portions with the surface of the recording medium is positioned on the upstream side of a sliding point of the slider on the recording medium in the recording medium movement direction.
