Load beam with sag control region and head gimbal assembly having the same and method of operating the head gimbal assembly in hard disk drive

摘要

Off-control the deflection region the load beam and a head gimbal assembly and a method of operating a hard disk drive having the same with a reduction of the motion track is disclosed. It disclosed the load beam to minimize the impact of disk vibration from the surface of the rotating disk during the track following operation. To this end, the load beam is bent toward the surface of the disk that when access to the tracks on the disk surface provided with a bending control region to provide a concave plate between the hinge mounts and the slider mount, the head gimbal assembly is rotated, the concave plate rotation by, flexure control region is adjusted to near the center of the inside of the disk to rotate the roll center of the head gimbal assembly. The head gimbal assembly compensates for vibration in the rotating disc surface through the roll center, reading or writing head to follow a track. Accordingly, the off-track motion is reduced is minimized track misalignment.
