Title: Magnetic transfering method
Inventor: NODA MAKOTO
IPC: G11B5/706
Filed: 1990-03-06
Abstract: PURPOSE:To obtain the excellent reproduced output of a slave medium even after repeated transfering by regulating relation between the residual coercive force Hr1 in a longitudinal direction of a master medium and the residual coercive force Hr2 in a vertical direction of the slave medium. CONSTITUTION:The residual coercive force Hr1, Hr2 is affected greatly by the coercive force Hc of magnetic powder to be used, the distribution of Hc, interaction between particles, degree of orientation and saturation magnetization quantity, and it does not always same as Hc. Accordingly, the master medium and the slave medium are regulated so as to be Hr1/Hr2>=2.0 by using Hr1,Hr2. At that time, the demagnetization of the master medium due to a bias magnetic field is reduced, and even after the repeated transfering, the reproduced output of the slave medium becomes favorable. The slave medium is provided with a magnetic layer whose media are the powder of MO.n(Fe2O3) (here, M is one of ba, Sr, Ca, and n = 5 to 6) and a binding agent such as vinyl chloride.vinyl acetate copolymer, etc.

Abstract: PROBLEM TO BE SOLVED: To enable highly accurate measurement regardless of the degree of a working speed by measuring a fluorescence output while a part irradiated with excitation light on the surface of a metal material is relatively moved to correct a measured value based on the relationship between the relative speed and correction factor. SOLUTION: A metal material 1 coated with a fixed amount of oil 2 is conveyed in the direction F by a metal material conveying device 3 to detect a conveying speed V(m/sec.) with a speed sensor 6. An applied oil amount measuring sensor 6 irradiates the surface of the metal material 1 with excitation light with a specified wavelength to detect a fluorescence output generated. The applied oil amount measuring sensor 6 runs horizontally to the metal material 1 in the direction G on a single rail 9 with an amount of applied oil measuring sensor traveling device 7. A speed sensor 11 detects a running speed Vc of the sensor and an arithmetic processing controller 12 computes a relative speed between the metal material 1 and the amount of applied oil measuring sensor 6 from detection signals of the speed sensors 5 and 11.
