 note = {Although the field of application of magnetic recording techniques is expanding from audio sound recording toward video, instrumentation, computer and so on, the principle of readout of stored information is unchangeable. Magnetoresistance effect of evaporated magnetic thin films, considered to have some possibility of application to information readout techniques, as well as magneto-optical effect, is experimentally studied in this paper. Main points in these experimental data are as follows: (1) Cobalt film has the highest magnetoresistance effect of typical magnetic materials and can be enlarged by oblique evaporation method and heating of substrata. (2) The transverse magnetoresistance effect of magnetic films is negative, drastically different from that of semiconductor. The longitudinal magnet oresistance effect is positive and five times as great as the transverse effect except for that of permalloy film. (3) The longitudinal magnetoresistance effect (the ratio of resistivity in rem anent magnetization state and that in demagnetizing state) increases line arly with coercivity and decreases with remanent magnetization. This is desirable for high density magnetic recording. In the recording application, RZ recording system must be utilized, because 'resistivity' is scalar value. Otherwise, the transverse recording method must be utilized because the longitudinal magnetoresistance effect is much greater than the transverse effect., Article, 信州大学工学部紀要 28: 127-135 (1970)},
