| 摘 要： | 本文用镜像法分析再生过程中,从施加在记录磁介质上的记录磁化强度析出的磁通和耦合到再生磁头的磁通,根据两种回路磁阻不同的影响计算出交链于再生磁头线圈中的磁通.由此可求得,当具有模拟信号的记录磁介质进入再生磁头的前部空间时所产生的再生电压.计算结果表明,再生电压的幅值中包含着许多重要的记录损失参数.

| Abstract: | The flux emanated from the recorded magnetization impressed on the recording medium and flux coupled with the reproducing head can be found with the image method during reproducing. The flux linking the reproducing head coil iscalculated by referring to the fact that the magnetic reluctances of two circuitsare different. The reproducing voltage can then be determined when the recordedmagnetic medium with the simulation signals enters the front space of the reproducing head. Calculation results show that the many parameter losses of importance for analog recording existed in the reproducing voltage. |
