Magnetic head device and linear tape drive including a twin bimodal type actuator and a dampening structure
In general, the invention provides a magnetic head device and linear tape drive that widen the high frequency side of the servo range. In particular, the invention provides a magnetic head device comprising a magnetic head chip with multiple magnetic elements arranged for recording or playback of multiple tracks and a fine positioning structure that uses a bimodal construction that may widen the high frequency side of the servo range by increasing the resonant frequency of the magnetic head chip including the tracking structure and lowering the Q value of the resonance point. In addition, the invention includes a damping structure suitable for the fine positioning structure that improves high speed response by widening the range in which the magnetic head device can be used for a servo. The magnetic head device may use a linear tape drive method.
