Patent number: 6687099Abstract: The magnetoresistance effect element is of a multilayered structure having at least magnetic layers and an intermediate layer of an insulating material, a semiconductor or an antiferromagnetic material against the magnetic layers, and the magnetoresistance effect element has terminals formed at least on the opposite magnetic layers, respectively, so that a all the magnetic layers constituting the magnetoresistance effect element are opposed substantially at right angles to the recording surface of a magnetic recording medium. Therefore, the area of the magnetic layers facing the recording surface of the magnetic recording medium can be extremely reduced, and thus the magnetic field from a very narrow region of the high-density recorded magnetic recording medium can be detected by the current which has a tunneling characteristic and passes through the intermediate layer.Type: GrantFiled: October 15, 2002Date of Patent: February 3, 2004Assignee: Hitachi, Ltd.Inventors: Ryoichi Nakatani, Masahiro Kitada, Naoki Koyama, Isamu Yuito, Hisashi Takano, Eijin Moriwaki, Mikio Suzuki, Masaaki Futamoto, Fumio Kugiya, Yoshibumi Matsuda, Kazuo Shiiki, Yoshinori Miyamura, Kyo Akagi, Takeshi Nakao, Hirotsugu Fukuoka, Takayuki Munemoto, Tokuho Takagaki, Toshio Kobayashi, Hideo Tanabe, Noboru Shimizu

Publication number: 20030099038Abstract: A highly reliable thin film filter for an optical multiplexer/demultiplexer is disclosed, in which defects such as chips or cracks hardly occur in an optical thin film. The thin film filter consists of a glass base plate and the optical thin film formed on the glass base plate surface. A side surface of the optical thin film is at an acute angle, preferably at an angle of 6 to 60 degrees, with the glass base plate surface at a crossing point between the optical thin film side surface and the glass base plate surface on a plane perpendicular to the glass base plate surface. After the optical film is formed on the glass base plate surface and the optical thin film side surface is made by dry-etching, an individual thin film filter element is made by cutting the glass base plate with a dicer or the like. Defects such as chips or cracks do not occur on the optical thin film side surface, since the optical thin film is not cut during the cutting of the glass base plate.Type: ApplicationFiled: November 14, 2002Publication date: May 29, 2003Applicant: HITACHI METALS, LTD.Inventors: Hideji Takahashi, Takashi Sato, Toshio Kobayashi, Shin Noguchi
