Latest Patents

Griffith holds a patent for a "Servo controlled magnetic head positioner." This invention features a magnetic recording head positioning system that utilizes a Terfenol-D magnetostrictive rod. The rod is prestressed by a lever arm, allowing it to operate within a linear range for micropositioning the magnetic recording head. The system is designed to respond to an electromagnetic field, which is applied to the rod by a coil based on a position error signal derived from servo data tracks on magnetic tape. The mechanical advantage provided by the lever arm amplifies changes in the magnetostrictive rod, enabling precise positioning of the head. Additionally, a permanent magnet system biases the magnetostrictive element with a DC field, facilitating bi-directional motion of the magnetic recording head while reducing coil current and size requirements.
