SLIDER FOR REDUCING AN OFF-TRACK MOTION OF A HEAD CAUSED BY A DISK VIBRATION, A HEAD GIMBAL ASSEMBLY AND AN ACTUATOR ASSEMBLY COMPRISING THE SLIDER AND THE HEAD GIMBAL ASSEMBLY, ESPECIALLY RELATED TO LOWERING A ROLL CENTER POSITION OF THE HEAD THAN ENTIRE THICKNESS OF THE SLIDER, WHILE REDUCING OFF-TRACK DISPLACEMENT

摘要

PURPOSE: A slider for reducing an off-track motion of a head caused by a disk vibration, an HGA(Head Gimbal Assembly) and an actuator assembly comprising the slider and the HGA are provided to lower an available roll central position of a slider than slider thickness, thereby decreasing an off-track motion caused by a disk vibration. CONSTITUTION: A slider(100) has an indented surface(104) to lower a roll center of an HGA than thickness of the slider(100). The HGA configured with the slider(100) can reduce off-track displacement caused by a disk vibration. A gimbal(300) disposed on a load beam(80) is contacted with the indented surface(104), and forms a slider roll center lower than the slider thickness. The slider(100) includes a slider contact cover(102) contacted with the gimbal(300). The slider contact cover(102) is coupled with the slider(100) through the indented surface(104). An actuator assembly comprises the HGA.
