ABSTRACT:
A broadband transmission path apparatus connects a head IC and a head in a suspension. Either one of the head IC and the head is assumed as a transmission terminal and the other is assumed as a reception terminal to divide a required transmission frequency band into at least two, one of which is assumed as a low band transmission path for low frequency transmission band and the other of which is assumed as a high band transmission path for high frequency transmission band. The high band transmission path forms a resonant circuit by a resistor component, an inductance component and a capacitor component of the transmission path itself, and realizes the high frequency transmission band characteristic by a resonant frequency characteristic of the resonant circuit.
