PURPOSE:To prevent the deterioration of S/N due to the fluctuation of the power supply voltage and to obtain a stable 1-output waveform, by setting a holding magnetic field in the direction opposite to the strobe point phase that discriminates ''1'' or ''0'' and reducing the intensity of a rotary magnetic field with the strobe point phase. CONSTITUTION:A holding magnetic field Hh is used to reduce the intensity HR of a rotary magnetic field in the vicivity of a strobe point thetat. The field HH always acts on a plane xy of a chip, and accordingly a rotary magnetic field HR' acting on the chip is subjected to be eccentric. The effective rotary magnetic field H'R is synthesized with the field HR applied from outside and the field Hh, and the center O' of the field H'R is shifted to the y direction, i.e., the start/stop direction, by an equivalent strength of the field Hh. Therefore the intensity of the effective rotary magnetic filed HR' is reduced at the position in the vicinity of the phase thetat. |
