Thin-Film Magnetic Head Having Microwave Magnetic Exciting Function And Magnetic Recording And Reproducing Apparatus

A magnetic recording and reproducing apparatus with a thin-film magnetic head having microwave magnetic exciting function, comprising:

• a magnetic recording medium having a magnetic recording layer;
• a thin-film magnetic head having a write magnetic field production means for producing, in response to a write signal, a write magnetic field to be applied into said magnetic recording layer of said magnetic recording medium, and at least line conductor of a microwave radiator of a plane-structure type, formed independent from said write magnetic field production means, for radiating, by feeding there through a microwave excitation current, a microwave band resonance magnetic field with a frequency equal to or in a range near a ferromagnetic resonance frequency FR of said magnetic recording layer of said magnetic recording medium;
• a write signal supply means for supplying the write signal to said write magnetic field production means;
• and
• a microwave excitation current supply means for supplying the microwave excitation current to said microwave radiator.
