以往的静电录音技术一般都是利用驻极体或铁电特性,使录音材料产生极化或者利用绝缘体表面荷电的原理.这些办法所制成的录音缺乏耐久性.本文介绍的静电录音系统采用的是把电荷图案渗入绝缘材料的方法.这种录音是耐久的,且可反复地重放.早期的实验证明,在往入电荷时,如果能使录音带的正反两面相对应的点上产生大小相等而符号相反的电荷,则录音效果是最为有利的.现在这个理想是通
The previous electrostatic recording technology are generally the use of electret or ferroelectric properties, the recording material polarization or the use of the insulator surface charge principle. These methods are made of recording lack of durability. This article describes the use of electrostatic recording system Is the method of infiltrating the charge pattern into the insulating material. This recording is durable and reproducible. Earlier experiments have shown that when a charge is applied, if the recording tape is made at the point corresponding to both the front and the back The same size and opposite sign of the charge, then the recording effect is the most favorable. Now the ideal is through
