Two-degree-of-freedom control scheme for flying-height and tracking-position controls with thermal actuators in HDDs

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
To improve positioning accuracy of a magnetic head in hard disk drives (HDDs), a triple-stage-actuator system was proposed with a thermal positioning actuator for a magnetic head positioning system. This positioning system has three types of actuators: a

Production Networks in Asia: A Case Study from the Hard Disk Drive Industry [PDF]

, 2011
Production networks have been extensively developed in East Asia. Previous studies on production networks used international trade data or input-output tables, but such aggregate data cannot explain how the networks actually operate.
