Conductive trace flexure for a magnetic head suspension assembly
摘要:
A magnetic head suspension assembly (10) for transducing data from and onto a surface of a rotating magnetic disk (4) includes a load beam (12) for supplying a directed force to a slider (16), so as to maintain the slider (16) at a desired height above the disk surface. A flexure (14) is secured to the load beam (12), and is formed of a flexible dielectric layer (55) on which a pattern of conductive traces (57-60) are formed. These conductive traces (57-60) are patterned for providing sufficient flexibility in various degrees of movement and stiffness to resist physical deformation, for imparting optimal mechanical and structural support to the slider (16) and to the load beam (12), and for electrically connecting the slider (16) to read/write electronic circuitry. In the preferred embodiment, the dielectric layer (55) is made of a polymeric resinous material, such as polyimide, and the conductive traces (57-60) are made of copper.
