A magnetic recording-reproducing circuit in a camera includes a magnetic head for reproducing information recorded on a magnetic recording portion, a first amplifying circuit having at least two input ends, the output of the magnetic head being connected to one of the input ends of the first amplifying circuit, a second amplifying circuit having at least two input ends, the output of the magnetic head being connected to one of the input ends of the second amplifying circuit, a first impedance for connecting the other input end of the first amplifying circuit and the other input end of the second amplifying circuit together, a second impedance for connecting the other input end and the output end of the first amplifying circuit together, and a third impedance for connecting the other input end and the output end of the second amplifying circuit together. The circuit also includes first and second comparison circuits and a binarization circuit for binarizing information recorded on the film on the basis of outputs of the first and second comparison circuits.
