Title:
磁気ヘッド装置及びリニアテープドライブ装置
Document Type and Number:
Japanese Patent JP4152903
Kind Code:
B2
Abstract:
In general, the invention provides a magnetic head device and linear tape drive that increase the resonant frequency and the range of a servo system. In particular, the invention provides a magnetic head device comprising a magnetic head chip with multiple magnetic head elements that is a structural part of the fine positioning system which allows the magnetic head elements follow the data tracks on the linear magnetic tape. Consequently, weight is reduced thereby increasing the resonant frequency and servo bandwidth. In another embodiment, the invention provides a magnetic head comprising bimodal actuators that are formed into an S shape and displaced by applying voltage where the polarization direction is opposite from one end to the other. In particular, the head chip may remain stable and may be driven dynamically thereby allowing the mechanical resonance of the bimodal actuator (including the head chip) to increase to 1 kHz or higher.
