摘要： A flexible magnetic disk drive is disclosed which has a transducer head requiring little or no positional or angular readjustment for proper data transfer contact with a flexible magnetic disk in the face of possible dimensional or mounting errors. The transducer head has a rounded contact surface for data transfer contact with the flexible magnetic disk, in which surface is defined a transducing gap, typically a read/write gap. The transducing gap is offset toward the axis of the magnetic disc from a notional line right angularly crossing, at the apex of the contact surface, another notional line connecting the apex of the contact surface and the center of the magnetic disk. So positioned on the contact surface, the transducing gap is practically free from the wobbling motion of that part of the rotating magnetic disk which is radially outward of its points of contact with the transducer head and with a pressure pad. The transducing gap can be arranged on the contact surface as above merely by mounting a transducer head of standard construction in a slanting attitude on a carriage which transports both the head and the pressure pad radially of the magnetic disk.

摘要翻译： 公开了一种灵活的磁盘驱动器，其具有换能器头，其需要很少或没有位置或角度重新调整，以在面对可能的尺寸或安装误差的情况下适当地与柔性磁盘的数据传输接触。 换能器头具有用于与柔性磁盘进行数据传输接触的圆形接触表面，其中表面定义为换能间隙，通常为读/写间隙。 换能间隙从接触表面的顶点处的直角成角度的理想线偏转到磁盘的轴线，另一个连接接触表面的顶点和磁盘中心的名义线。 因此，位于接触表面上的换能间隙实际上没有旋转磁盘的与转换器头部接触的径向外侧的一部分的摆动运动以及压力垫。 换能间隙可以如上所述地设置在接触表面上，只是通过将标准结构的换能器头部以倾斜的姿态安装在将磁头和压力垫两端的磁盘输送到磁盘的径向上的托架上。
