Abstract

PURPOSE:To reduce the manufacturing cost with a simple constitution, by using the reproduction head in which the thin film magnetic resistance effect element at non- bias magnetic field is located so that the film surface is orthogonal to the film surface of the recording media. CONSTITUTION:The reproduced output of the reproducing head 1 is inputted to the differentiating circuit 3 after being amplified at the amplifying circuit 2. The output signal of the circuit 3 is inputted to the comparison circuit 4 in which it is digitized with a suitable bias voltage at leading and also digitized at zero level at trailing, and the output of the circuit 4 is inputted to the trailing pulse formation circuit 5 since the trailing of the output pulse is only used. The output pulse of the trailing pulse formation circuit 5 is inputted to the discrimination circuit 6 to perform discrimination of the digital binary information, and the output pulse discriminated is fed to the serial parallel conversion circuit.
