摘要: A circuit for reading a toll road ticket in which a mark for magnetic recording density discrimination formed on a ticket is detected and a magnetic record demodulating circuit is selected in accordance with the result of detection. The circuit is a digital recording circuit and reproducing circuit for a magnetic card utilizing modified frequency modulation. In a toll receiving system of a toll road, coexistence of tickets adopting different magnetic recording densities or recording systems is made possible.
