Claims
- 1. A magnetic head suspension assembly including an air bearing slider and at least one transducer disposed on said slider for transducing data that is recorded and read out from a surface of a rotating magnetic disk drive comprising:
- a single integral planar piece of a specified thickness comprising,
- a load beam section formed with a narrowed end;
- a flexure section formed with two spaced narrow legs defining a cutout portion therebetween, said legs extending from said narrowed end of said load beam section, and a lateral ear spaced from said load beam section connecting said legs;
- a tongue extending from said end of said narrowed load beam section, said tongue being disposed between said legs of said flexure section, said tongue having a free end within said flexure section, said tongue being formed with a load dimple;
- said air bearing slider being bonded to said lateral ear and in contact with said load dimple;
- whereby load transfer is effectively separated from the gimballing action of said slider so that pitch and roll stiffness is effectively reduced.
- 2. An assembly as in claim 1, wherein said head slider has a top non-air bearing surface attached to said flexure section.
- 3. An assembly as in claim 2, including means formed with said lateral ear for supporting said attached head slider.
- 4. An assembly as in claim 3, wherein said supporting means comprises outriggers or a split tongue.
- 5. An assembly as in claim 3, wherein said supporting means comprises said lateral ear that connects said narrow legs.
- 6. An assembly as in claim 2, wherein said slider is about 0.0110 inch high, 0.0400 inch long and 0.0200-0.0260 inch wide.
- 7. An assembly as in claim 2, wherein said top non-air bearing surface of said slider is formed with a platform and step adjacent to said platform.
- 8. An assembly as in claim 7, wherein said platform of said slider is about 0.0336 inch long and said step is about 0.0015 inch high.
- 9. An assembly as in claim 2, including a load dimple formed in said tongue.
- 10. An assembly as in claim 9, wherein said load dimple is hemispherical in shape and faces down into contact with said top surface of said slider.
- 11. An assembly as in claim 1, wherein said single integral planar piece including said tongue is about 0.0012 to 0.0015 inch thick and said narrow legs are about 0.0010 inch thick.
- 12. An assembly as in claim 1, wherein said load beam section is shaped as a truncated triangle.
- 13. An assembly as in claim 1, including a mount section at the rear end of said load beam section for enabling mounting said suspension to an actuator arm; and
- a leaf spring section between said rear mount section and said load beam section for providing flexibility to said suspension.
- 14. An assembly as in claim 13, including a swage plate joined to said mount section for providing rigidity to said rear end of said suspension assembly.
- 15. An assembly as in claim 13, including front flanges formed along the edges of said load beam section and rear flanges formed along the edges of said rear mount section with a hiatus between said front and rear flanges.
- 16. An assembly as in claim 15, wherein said front flanges are formed with shallow U-shaped channels, and electrical wiring without tubing is positioned within said channels.
- 17. An assembly as in claim 13, including a cutout in said leaf spring section for providing flexibility to said suspension.
- 18. An assembly as in claim 1, further including an apertured extension formed at the rear end of said suspension assembly for enabling attachment to an actuator of a disk drive without a separate head arm to enable pivoting of said suspension assembly.
- 19. An assembly as in claim 1, including a damping material on said load beam.
- 20. An assembly as in claim 1, including at least one load/unload tab formed at the sides of said load beam section.
- 21. An assembly as in claim 2, wherein said top non-air bearing surface is substantially flat.
- 22. An assembly as in claim 21, wherein said lateral ear includes bent sections for contacting with said top surface of said slider.
