阻抗是磁头最基本和最重要的电气参数之一,它不仅是磁头在整个生产过程中各生产工序主要的质量控制、检测和管理参数,而且是整机设计者设计录音机电路时必须依据的参数之一。它不仅是磁头阻抗分类的依据,而且是洞察磁头其它电气指标的窗口。可见,了解磁头的阻抗特性对磁头制造者和整机电路设计者都是必要的。这里着重从应用角度出发来探讨磁头的阻抗特性。
Impedance is one of the most basic and important electrical parameters of the head. It is not only the main quality control, testing and management parameters of the head during the whole production process, but also the parameters that the designer of the machine must design when designing the circuit of the recorder one. It is not only the basis for the classification of the head impedance, but also the window to see the other electrical specifications of the head. Visible, understand the impedance characteristics of the head of the head manufacturers and circuit designers are necessary. Here focused from the application point of view to explore the impedance characteristics of the head.
