Magnetic disk drive with integrated electrical conductors for recording element

摘要

The magnetic disk apparatus includes an electric wiring capable of satisfying an electric condition under which high frequency recording higher than or equal to 200 MHz can be accomplished. A magnetic head having at least a recording device for recording to a magnetic recording medium is provided as well as an electric wiring corresponding to a recording current supplying device for this magnetic head are formed on a suspension member for mechanically suspending the magnetic head. The recording current is supplied to a magnetic head recording device by employing such electric wiring, the characteristic impedance of which is higher than a maximum impedance of the magnetic head recording device.
