摘要:
A gimbal head assembly and an actuator having the same, the gimbal head assembly and the actuator being included in a hard disk drive (HDD). The actuator can include a swing arm rotatably installed on a base member, the head gimbal assembly elastically biasing a read/write head towards a surface of a disk, and a voice coil motor rotating the swing arm. The head gimbal assembly can include a load beam attached to the swing arm, a flexure attached to the load beam, a slider mounted on a slider mounting portion of the flexure and comprising a read/write head installed on the slider, and an air foil disposed in front of the slider and guiding air flow generated due to rotations of the disk along both sides of the slider. The air foil reduces turbulent air flow in the vicinity of the slider, thereby reducing oscillations of the slider due to the turbulent air flow
