    • A magnetic head having an upper head and a lower head disposed opposite to each other and capable of simultaneously reading information from or writing information in both sides of a magnetic disc inserted therein. The upper head is fixed to a wingable arm at correct vertical position and inclination, while the lower head is mounted through a gimbals spring on a carriage which is slidable along a guide rod or guide rods in the radial direction of the magnetic disc. Since the upper head is positioned correctly and the surface thereof facing the lower head serves as a datum surface, the inclination of the lower head need not be adjusted in assembling the magnetic head, and thereby the process for assembling the magnetic head is remarkably simplified.
    • 一种磁头,其具有彼此相对设置的上磁头和下磁头,并且能够同时从插入其中的磁盘的两侧读取信息或写入信息。 上头部以正确的垂直位置和倾斜度固定到可机翼臂上,而下头部通过万向弹簧安装在滑架上,托架可沿导向杆或导杆沿着磁盘的径向方向滑动。 由于上部头部正确定位并且其面向下部头部的表面用作基准面,所以在组装磁头时不需要调整下部头部的倾斜度,从而显着简化了用于组装磁头的过程。

    • A magnetic head assembly including a carriage which carries thereon a first magnetic head for information writing and reading to and from one side of a disc-like magnetic recording medium, and a hold case which carries thereon a second magnetic head for information writing and reading to and from the other side of the magnetic recording medium, the second magnetic head being disposed in a position opposed to the first magnetic head, the hold case being connected to the carriage through hinge means rotatably to a certain degree relative to the carriage, and the magnetic head assembly being reciprocated in a radial direction of the magnetic recording medium. The first magnetic head is mounted on the carriage through a gimbal spring which is formed rotatably to a certain degree with respect to biaxial hinge portions, and the second magnetic head is mounted on the hold case through a spring plate which is formed rotatably to a certain degree with respect to a uniaxial hinge portion. The hold case is urged toward the carriage on the side of the hinge means rotatably to a certain degree relative to the carriage.
    • 一种磁头组件,包括:托架,其承载有用于向盘状磁记录介质的一侧进行信息写入和读取的第一磁头;以及保持壳体,其承载用于信息写入和读取的第二磁头 并且从磁记录介质的另一侧开始,第二磁头设置在与第一磁头相对的位置,保持壳体通过铰链装置通过铰链装置相对于滑架可旋转地连接到一定程度, 磁头组件在磁记录介质的径向方向上往复运动。 第一磁头通过相对于双轴铰链部可旋转地形成一定程度的万向弹簧安装在滑架上,第二磁头通过弹簧板安装在保持壳上,弹簧板可旋转地形成一定的 相对于单轴铰链部分。 保持壳体相对于滑架以一定程度的旋转自如地被推向铰链装置侧的滑架。
