Abstract
A multi-layer magnetic recording medium and a method for making a multi-layered magnetic recording media as described. The recording medium has magnetic inner layer with magnetic particles having a specific squareness ratio and saturation magnetization which results in superior high frequency output and improved overwrite characteristics. The method for making a magnetic recording medium involves controlled, partial drying of the inner layers to avoid intermixing of the respective layers while facilitating efficient fabrication.
