PROCESS FOR GENERATING A LATENT MAGNETIC IMAGE |
摘要 |
In forming a latent magnetic image by imagewise demagnetization of a magnetized layer, less than the entire thickness of the exposed area is demagnetized so as to induce a magnetization of opposite polarity in the demagnetized area, thus reducing the net strength of the residual and induced magnetic fields within the exposed areas. |
