Load beam having an additional bend in a head-gimbal assembly
First Claim
Patent Images
1. A load beam for coupling a gimbal to a support arm in a head-gimbal assembly, comprising:
- a resilient section with a first end for attachment to the support arm and a second end, and having a plurality of preformed bends between the first and second ends wherein each preformed bend is perpendicular to a line that extends longitudinally between the first end and the second end and follows a surface of the load beam and wherein each preformed bend bends in approximately a same direction; and
a substantially rigid section having a first end coupled to the second end of the resilient section and a second end for attachment to the gimbal.

Abstract
A load beam couples a gimbal to a support arm in a head-gimbal assembly. A resilient section has a first end for attachment to the support arm and a second end. The resilient section also has a plurality of preformed bends between the first and second ends. A substantially rigid section has a first end coupled to the second end of the resilient section and a second end for attachment to the gimbal.

7. A head-gimbal assembly (HGS) connected to a support arm for movign the HGA about an axis of rotation in a magnetic recording system where information is recorded on and retrieved from a magnetic disk, comprising:
-
transducer means for recording and retrieving the information; slider means, coupled to the transducer means, for providing a lifting force to allow the transducer means to fly over the disk; gimbal means, coupled to the slider means for providing a resilient connection to the slider means; load beam means, coupled to the support arm and the gimbal means, for supplying a load force to counteract the lifting force provided by the slider means, the load beam means having a plurality of preformed bends generally perpendicular to a line extending between the gimbal means and the support arm wherein at least two of the preformed bends are bent in approximately a same direction. - View Dependent Claims (8, 9, 10, 11, 12)
