摘要： A magnetic-tape apparatus has a magnetic-head unit with a magnetic head having a head face for guiding a magnetic tape. The magnetic head has transducing gaps for writing and/or reading information onto/from the magnetic tape. The magnetic-head unit further comprises two height limiters having tape-guide surfaces for guiding an edge of the magnetic tape. A tangent line, which is tangent to both tape-guide surfaces, extends perpendicularly to an imaginary line in the head face and passing through the transducing gaps. If an edge of the magnetic tape is in contact with the two height limiters, the position of the magnetic tape relative to the magnetic head is always the same, so that no azimuth errors can arise. In order to bring this edge of the magnetic tape into contact with the height limiters, the magnetic-head unit is mounted so as to be pivotable about an axis perpendicular to a tangent plane to the head face at the location of the transducing gaps. This axis extends through the center of gravity of the magnetic-head unit.
摘要翻译：磁带装置具有磁头单元，磁头单元具有用于引导磁带的磁头面的磁头。磁头具有用于向/从磁带写入和/或读取信息的换能间隙。磁头单元还包括两个高度限制器，其具有用于引导磁带边缘的带引导表面。与两个带引导表面相切的切线垂直于头部表面中的假想线延伸并且穿过换能间隙。如果磁带的边缘与两个高度限制器接触，则磁带相对于磁头的位置总是相同的，从而不会产生方位误差。为了使磁带的这个边缘与高度限制器接触，磁头单元安装成在换能间隙的位置处绕垂直于切平面的轴线枢转到头部面。该轴线延伸穿过磁头单元的重心。

摘要： A transmission with variable mechanical prestress including a pinion driven by an electric motor, a driven gearwheel with its bearings in a housing, and an electromagnetic actuator for applying a prestress force which is controllable in dependence on an instantaneous load to be handled by the transmission. The electric motor with the pinion is supported so that it can be tilted relative to the housing. Owing to a tilting movement of the electric motor caused by the actuator, the pinion is pressed against the gearwheel with a certain prestress force in a radial direction. The transmission is free from play, while the virtual play arising from friction and hysteresis is strongly reduced, and the positioning accuracy is enhanced as a result.
摘要翻译：具有可变机械预应力的变速器包括由电动机驱动的小齿轮，其轴承在壳体中的从动齿轮和用于施加可根据由变速器处理的瞬时负载来控制的预应力的电磁致动器。具有小齿轮的电动机被支撑成能够相对于壳体倾斜。由于由致动器引起的电动机的倾斜运动，小齿轮在径向方向上以一定的预应力压靠在齿轮上。变速箱不起作用，而由摩擦和滞后引起的虚拟动作大大降低，结果提高了定位精度。
