本文叙述在記录单位脉冲信号情况下,磁头内的磁場强度的計算方法。文中给出在不接触記录情况下的用以确定时间特性的持續时間、信号鉴别率、讀出脉冲幅度所得出的公式。引出关于鉴别率及讀出脉冲幅度与写入状态、磁头前問隙尺寸、載磁体(磁层)-磁头之間空隙、磁层成分的实驗数据。并研究了通过线性网絡的讀出脉冲傳輸特性。
This article describes the calculation of the magnetic field strength inside the head in the case of a recording unit pulse signal. The paper gives the formula for determining the duration of the time characteristic, the signal discrimination rate, and the amplitude of the readout pulse in the absence of contact recording. The experimental data about the identification rate, read pulse amplitude and write state, the size of the head gap, the gap between the magnetic carrier (magnetic layer) and the magnetic head and the composition of the magnetic layer are introduced. And studied the read pulse transmission characteristics through the linear network.
