Method for preparing a magnetic recording medium

摘要

A method for preparing a magnetic recording medium comprising the steps of pre-dispersing ferromagnetic particles and a binder in a solvent, mixing and dispersing with an additional binder, and coating thus obtained magnetic coating composition on a support, wherein said ferromagnetic particles having a specific surface area SBET of 40 m2/g or more and an absorved moisture content of less than 0.8 wt. % are pre-dispersed in said solvent containing cyclohexanone in an amount of 80 wt. % or more.
