An active slider with an H-shaped PZT and a U-shaped or grooved slider body is proposed for flying height control. The active slider has a decoupled crown and camber adjustment to improve the flying height adjustment ability. It can achieve more than 2nm flying height adjustment with a 12V voltage input.
