Magnetic disc moving direction discrimination circuit diagram composed of magnetosensitive resistance

Published:2011/5/9 2:24:00 Author:Nicole | Keyword: magnetic disc, moving direction, discrimination, magnetosensitive resistance

The figure1 is a magnetic disc moving direction discrimination circuit which is composed of magnetosensitive resistance. In the circuit, R(M1) and R(M2) are magnetosensitive resistances, in order to improve the temperature characteristic of magnetosensitive resistance, it should adopt series connection. When the magnetic disc A moves, VT1 turns on, the collector outputs pulse singal which is shown in the figure1(c). If the magnetic disc continues to move, it keeps away from R(M1) and approaches R(M2), then VT1 turns off, VT2 turns on. According to the change of magnetic field, VT1 and VT2 output pulse singal which is shown in the figure1(c). So, it can judge the magnetic disc's direction of movement according to the sequence of pulse singal.   (View)
