Title: Magnetic card
Inventor: SUGIURA MIKIO
IPC: C09D127/06
Filed: 1991-04-16
Abstract: PURPOSE:To prevent forgery of the card by providing a magnetic layer in which a bipolar peak voltage of an analog reproduction waveform is asymmetrical when magnetic information which is subject to unidirectionally DC saturation magnetization and is recorded is reproduced. CONSTITUTION:A residual magnetization direction 5 by DC saturation magnetization on a magnetic card when the magnetic card is applied to a magnetic card reader writer from a direction with a magnetic pole at the end of the magnetic card in the lengthwise direction to be the S pole, a signal magnetization 4 and a reproduced waveform 6 are shown in figure. When the magnetization 4 and the direction 5 by DC saturation magnetization are the same, the signal magnetization is strengthened and the reproduction output is increased. When the magnetization 4 and the direction 5 are opposite, the signal magnetization is weakened and the reproduction output is decreased. Then in this case, the reproduction output in the positive direction is increased. When the relation is opposite, the reproduction output in the negative direction is increased. The asymmetricity of the bipolar peak voltage is remarkable and since the degree of the asymmetry depends on the recording current, it is difficult to rewrite the magnetic information in matching with the reproduction output level.
