    • There is provided a carriage assembly of a hard disk drive where a convex pattern that makes it possible to mount a magnetic head with high precision in parallel on a gimbal is provided on the gimbal and where it is possible to use the same convex pattern regardless of whether a U-shaped pressing member is used or a pressing member shaped like geta teeth is used as the pressing member when mounting the magnetic head on the gimbal, which makes it unnecessary to redesign the convex pattern in accordance with the construction of a magnetic disk and thereby reduces the design cost. Joining portions, which are composed of part of the wiring circuit and are used to join the connection terminals of the magnetic head, and two protruding bar-shaped portions, which support the magnetic head and are formed along both edges of a bonding portion of the gimbal for the magnetic head that are perpendicular to an end surface of the magnetic head where the connection terminals are formed, are formed on the surface of the gimbal on which the wiring circuit is formed. The magnetic head is bonded to the bonding portion by adhesive applied between the two protruding bar-shaped portions of the bonding portion.
    • 提供了一种硬盘驱动器的托架组件,其中可以在万向节上并联安装高精度平行的磁头的凸形图案,并且可以使用相同的凸形图案,而不管 在将磁头安装在万向架上时,是否使用U形按压构件或者形成像牙齿的按压构件作为按压构件,这使得不需要根据磁盘的结构重新设计凸起图案 从而降低设计成本。 接合部分由布线电路的一部分组成,用于连接磁头的连接端子,以及两个突出的棒状部分,其支撑磁头并且沿着两端的接合部分的两个边缘形成 形成在与构成连接端子的磁头的端面垂直的磁头的万向节形成在形成布线电路的万向节的表面上。 磁头通过粘合剂粘结在粘合部分上,粘合剂粘合在粘结部分的两个突出的棒状部分之间。

    • A discrete Kalman filter 12 and a disturbance estimating unit 13 are added to a feedback loop for feeding back a detected value of position from a position detector 6. The Kalman filter estimates position and velocity of an object to be controlled, thereafter outputting an estimated value of position and an estimated value of velocity. The disturbance estimating unit estimates from a command value of current and the estimated value of velocity the disturbance that is added to a load 5. The estimated value of position is fed back to a position controller 1, and the estimated value of velocity is fed back to a velocity controller 2. Further, a difference between a target value of current outputted from the velocity controller and the estimated value of disturbance is output as the command value of current.
    • 将离散卡尔曼滤波器12和干扰估计单元13添加到用于从位置检测器6反馈检测到的位置值的反馈回路。卡尔曼滤波器估计要控制的对象的位置和速度,然后输出估计值 的位置和速度的估计值。 干扰估计单元从电流的指令值和速度的估计值估计加到负载5上的干扰。将估计的位置值反馈到位置控制器1,并且将估计的速度值反馈 另外,输出从速度控制器输出的电流的目标值与估计的干扰值之间的差作为电流的指令值输出。
