PURPOSE:To realize an inerasable soft tape, by manufacturing the soft tape by distributing magnetic particles in accordance with the intensity of signals. CONSTITUTION:An applying process shown by the (a) of the figure is provided in the manufacturing process of a magnetic tape. In this process a drum A is magnetized with a laser light B proportional (correlative) to the intensity of signals and magnetic powder C contained in a solvent is adhered to the drum A proportionally to he intensity of the laser light B. The magnetic powder adhering to the drum A is transferred to a base D for magnetic tape. The soft tape manufactured in such a way cannot be erased even when an intensive magnetic field is applied and, therefore, a tape required in special uses can be realized. |
