摘要： A head gimbal assembly includes a magnetic head slider provided with a recording head element that applies a recording magnetic field to a magnetic recording medium and a suspension that supports the magnetic head slider. The magnetic head slider further includes a microwave radiation element that radiates a microwave magnetic field from a microwave excitation current that is supplied from a microwave generating circuit, and that applies the microwave magnetic field to the magnetic recording medium when the recording head element applies the recording magnetic field to the magnetic recording medium. The suspension includes a microwave transmission line that transmits the microwave excitation current, and the microwave transmission line is provided with a matching circuit to achieve impedance matching with the microwave radiation element.

摘要： At least one of a rise time and a fall time of a dielectric resonator oscillator are reduced. The dielectric resonator oscillator includes a dielectric resonator, a drive circuit for applying a resonance voltage to the dielectric resonator, a switch for applying a voltage required for generating the resonance voltage to the drive circuit, a switch for applying a ground voltage for stopping generation of the resonance voltage to the drive circuit, and a capacitor connected to a power terminal side that supplies a voltage, as seen from the switch, for removing noise generated by the drive circuit. If these switches are made conductive exclusively, oscillation can be stopped immediately by turning on the switch. Since the capacitor is in a charge storage state at all times, regardless of ON/OFF of the switch, the oscillation operation can be started immediately when the switch is turned ON.

摘要： A magnetic head includes a slider having a thin-film magnetic element disposed at a trailing end of a surface of the slider opposite a magnetic recording medium. The slider has side surfaces that may be substantially perpendicular to the surface opposite the recording medium and may extend in a direction in which the slider moves relative to the recording medium and inclined surfaces disposed between the surface opposite the recording medium and the side surfaces. The inclined surfaces may form obtuse angles with the surface opposite the recording medium and the side surfaces.
