    摘要: A magnetic head which includes a core, a coil wound on the core, terminals to which ends of the coil are connected. The magnetic head also includes a substrate on which mounted are a demodulating electronic component for demodulating an analog output signal output from the terminals to create a digital demodulated signal, and an encrypting electronic component for encrypting the demodulated signal to create an encrypted signal. A cable electrically connects the demodulating electronic component and the terminals. A case body stores the core, the coil, the terminals, and the cable. The demodulating electronic component is mounted on one side of the substrate, and the encrypting electronic component is mounted on the other side of the substrate. The substrate is fixed to the case body so that the demodulating electronic component is placed inside the case body while the encrypting electronic component is placed outside the case body.
