| titleOfInvention | Magnetic field generator |
| abstract | (57) [Abstract] [Purpose] To develop a contact-type magnetic field generator that is less affected by frictional heat generated by sliding on an information recording medium. [Structure] A magnetic field generator (electromagnet) is composed of a yoke 14 made of a ferromagnetic material and a coil 15 wound around a part of the yoke 14. The yoke 14 is provided with outer yokes 14a, 14a that come into contact with the magneto-optical recording medium 11 when the medium is driven. b and a center yoke 14c which is not in contact with the magneto-optical recording medium 11, the tip portions of the outer yokes 14a and 14b are a medium sliding surface, and the tip portion of the center yoke 14c generates a recording magnetic field or an erasing magnetic field H. Part. The step s from the tip of the outer yoke to the tip of the center yoke is 1 to The thickness is preferably about 50 μm. |
