摘要： An information recording medium, a method of manufacturing the information recording medium, a read/write head, and a method of manufacturing the read/write head are provided. The information recording medium includes magnetic recording layers formed of a ferromagnetic substance and electrical recording layers formed of a ferroelectric substance. The read/write head includes an electromagnetic write head including a main pole, a return pole magnetically connected to the main pole but electrically isolated from the main pole, a magnetic field applicator which applies a magnetic field to the main pole, and a voltage source which applies a bias voltage to the main pole; a magnetic read head provided an a side of the electromagnetic write head; and an electrical read head provided on an other side of the electromagnetic write head.
