Abstract
PURPOSE: To increase the SN ratio, by improving the dispersibility of carbon black, through containing a specific carbon black in a magnetic layer.
CONSTITUTION: By containing a carbon black including 3wt% or more of voltage matter in a magnetic substance layer, the dispersibility of the carbon black is made excellent and the smoothness of the surface of magnetic substance layer can be improved. Even if the amount of carbon black used is more, the SN ratio can be increased.
