    • A head arm for use in a magnetic disk drive, comprising a guide arm disposed between a magnetic head and an actuator so as to transmit actuating force of the actuator to the magnetic head thereby guiding the magnetic head along a plane of a magnetic disk, a printed circuit fixed to the guide arm, and deflection compensating member for making the coefficients of thermal expansion of said guide arm and said printed circuit substantially equal to each other in at least the direction of seek of the head arm. No thermal deformation in an out-of-plane direction occurs on such a head arm regardless of any variation in the temperature of the environment in which the magnetic disk drive is installed. A head arm may also comprise a guide arm and a printed circuit formed of a moisture absorptive material and covered at all or part of its surfaces with a covering layer formed of a moisture resistive material not permeable to moisture. No deformation in an out-of-plane direction occurs on such a head arm regardless of any variation in the humidity of the environment in which the magnetic disk drive is installed. Therefore, the possibility of occurrence of off-track can be minimized.
    • 一种用于磁盘驱动器的头臂,包括设置在磁头和致动器之间的引导臂,以将致动器的致动力传递到磁头,从而沿着磁盘的平面引导磁头, 固定到引导臂的印刷电路和用于使所述引导臂和所述印刷电路的热膨胀系数至少在头臂的寻找方向上彼此基本相等的偏转补偿构件。 在这种头臂上不发生面外方向的热变形,而不管安装有磁盘驱动器的环境的温度如何变化。 头臂还可以包括引导臂和由吸湿材料形成的印刷电路,并在其全部或部分表面上覆盖由不透湿水分的防潮材料形成的覆盖层。 在这种头臂上不发生面外方向的变形,而不管安装有磁盘驱动器的环境的湿度是否变化。 因此,可以使偏离轨迹的发生的可能性最小化。

    • A magnetic disc memory device comprises a magnetic head support member pivotably mounted on a shaft, gimbals fixedly supported by one end of the magnetic head support member, a magnetic head core secured to the gimbals, and a magnetic disc for recording and reproducing informations through an action of the magnetic head core. A cam is arranged to be engaged by an end of a cancelling member which is effective to reduce the off-track to zero. The cancelling member is fixedly supported by the other end of the magnetic head support member in a manner to extend in a direction opposite to the gimbals, and is formed of a material having a thermal expansion coefficient equivalent to that of the material forming the gimbals.
    • 磁盘存储装置包括可枢转地安装在轴上的磁头支撑构件,由磁头支撑构件的一端固定支撑的万向节,固定到万向节的磁头芯,以及用于通过 磁头芯的作用。 凸轮被布置成由消除构件的端部接合,其有效地将偏离轨道减小到零。 取消构件以与万向架相反的方向延伸的方式由磁头支撑构件的另一端固定地支撑,并且由具有与形成万向架的材料的热膨胀系数相当的热膨胀系数的材料形成。
