摘要： PURPOSE:To obtain high reproduced output by suppressing the Barkhausen noise of a magneto-resistance effect element having transverse bias magnetic field and longitudinal bias magnetic field impressing means. CONSTITUTION:This magneto-resistance effect type reproducing head is provided with a soft magnetic film (SAL film) 30 for impressing bias magnetic fields, a nonmagnetic conductive film or insulating film 40 and a magneto-resistance effect film 20 on a substrate 70 and is provided with a pair of electrode films 10 via an antiferromagnetic film 80 on the magneto-resistance effect film 20. The ratio of the specific resistance and thickness of the electrode films formed on the magneto-resistance effect film is set at >=5OMEGA. As a result, the generation of the Barkhausen noise is sufficiently suppressed in the magneto-resistance effect type reproducing head which impresses the longitudinal bias magnetic field by the antiferromagnetic film.

摘要： PROBLEM TO BE SOLVED: To expand a receive margin in inductive coupling wireless communication between semiconductor chips.
SOLUTION: For example, a transmission semiconductor chip LSI_TX generates a current signal ISIG on a transmission coil L_TX in "1" level transmission and does not generate the ISIG in "0" level transmission. A semiconductor chip LSI_RX for receiving first resets the integration result of an integration circuit ITG by means of a reset switch RSW. Subsequently, a voltage signal VSIG induced associated with ISIG on a receive coil L_RX is amplified by means of an amplification circuit AMP. At the same time, the amplification result is integrated by means of the ITG. The integration result is latched by means of a latch circuit LT. Consequently, timing control should be made so that the VSIG is positioned within the time period TM from the operation of the RSW to the latch by the LT.

摘要： PROBLEM TO BE SOLVED: To solve the problem wherein it is difficult to produce an oblique anisotropic magnetic recording medium, even though oblique anisotropic medium has been proposed for solving the problems of the magnetic recording media, such as shortage of effective recording magnetic field and variations in reverse magnetic field.
SOLUTION: A magnetic disk 100 has a glass substrate 101, a soft magnetic backing layer (SUL) 102, and a recording layer 103. The soft magnetic backing layer (SUL) 102 has a waveform shape, having a sloped surface (sawtooth waveform shape, chevron shape), as viewed from a substrate surface 104. A direction A of the magnetic anisotropy of the recording layer 103, formed in the waveform-shaped soft magnetic backing layer (SUL) 102 becomes perpendicular with respect to the substrate surface 104. Meanwhile, the recording magnetic field is incident perpendicular with respect to the sloped surface of the soft magnetic backing layer (SUL) 102 so that the direction A of the magnetic anisotropy of the recording layer 103 can be sloped by an angle of α, with respect to a direction of the recording magnetic field. As a result, recording of an oblique anisotropic medium can be realized effectively.
