Abstract
A microwave-assisted magnetic recording and reproducing apparatus includes a microwave power generator, a microwave magnetic field generating element, and a thin film magnetic head that may record a data signal in high density in a magnetic recording medium that has a high coercivity. A magnetic recording medium, a magnetic head that records information in the magnetic recording medium, a microwave power generator provided independently of the magnetic head, and a differential signal supply unit used to supply microwave power generated by the microwave power generator as differential signals to a microwave magnetic field generating element provided at the magnetic head are included.
