| titleOfInvention | Active magnetic bearing device for improved servo control |
| abstract | (57) Abstract: An apparatus and method for controlling the position of a magnetically floating head (120) in an active magnetic bearing assembly (112) in a disk drive (100). A servo control circuit (166) applies a current to the actuator coil (113) to rotate the actuator, and the active magnetic bearing control circuit (168) applies a current to a bearing coil (208) to rotate the actuator. Floating. When an external disturbance is applied to the actuator, the active magnetic bearing control circuit provides a bearing translation (BT) signal to the servo control circuit to adjust the current applied to the actuator coil to compensate for the disturbance I do. Conversely, when the servo control circuit initiates a search operation, a search expectation (SE) signal is provided to the active magnetic bearing control circuit to adjust the current to the bearing coil to compensate for the torque force of the actuator. I do. |
