Abstract
A magnetic head supporting mechanism includes a head positioning actuator having an arm, and a load beam connected to the arm. The load beam has a gimbal. The gimbal includes a magnetic head slider fixing portion on which a magnetic head slider having a magnetic head is mounted, a first pair of beams extending from opposite sides of the magnetic head slider fixing portion along a traverse direction of the load beam perpendicular to a longitudinal direction thereof, and a second pair of beams respectively connected to the first pair of beams and extending so as to face the opposite sides of the magnetic head slider fixing portion.
Claims8
A head supporting assembly adapted to elastically support a head slider, said head supporting assembly comprising:
- a head slider fixing portion on which the head slider is mounted;
- first and second beams extending along a longitudinal direction of said head supporting assembly, said first and second beams being spaced apart and entirely separated from the head slider fixing portion;
- a third beam which connects an end of the head supporting assembly to a first end of the head slider fixing portion;
- wiring patterns attached to at least one of said first, second and third beams;
- and
- terminals formed on the head slider fixing portion and connected to said wiring patterns,
- wherein said wiring patterns are attached to a side of said head supporting assembly on which said head slider is located.
A load beam adapted for use in a magnetic disk drive, comprising:
- a suspension plate assembly having a gimbal portion at one end, said suspension plate assembly having at least one opening in the gimbal portion, said gimbal portion including at least three beam portions and at slider fixing portion adapted for mounting a head slider,
- wherein at least two of said beam portions are formed about a longitudinal center-line of said suspension plate assembly on either side of said slider fixing portion and are entirely separated from said slider fixing portion,
- wherein said slider fixing portion is connected to said suspension plate assembly only through a remaining beam portion and is flexibly supported only by said remaining beam portion,
- wherein said load beam further comprises wiring patterns attached to said suspension plate assembly, said slider fixing portion having terminals connected to said wiring patterns, and
- wherein said wiring patterns are attached to a side of said suspension plate assembly on which said head slider is located.
