摘要： A production method for a magnetic recording medium having a non-magnetic layer on a non-magnetic support, and a magnetic layer on the non-magnetic layer, the method comprising the steps of applying a non-magnetic layer-use coating onto a non-magnetic support and drying it to form a non-magnetic layer, then applying, onto the non-magnetic layer, a magnetic layer-use coating in excess of a target magnetic layer wet coating thickness by using a die nozzle coat, and scraping off the excessively applied magnetic layer-use coating down to the target magnetic layer wet coating thickness by a bar to form a magnetic coating.

摘要： A multi-layer magnetic recording medium (10) and a method for making a multilayered magnetic recording media as described. The recording medium has magnetic inner layer (13) with magnetic particles having a specific squareness ratio and saturation magnetization which results in superior high frequency output and improved overwrite characteristics and magnetic outer layer (14) containing ferromagnetic particles. The method for making magnetic recording medium involves controlled, partial drying of the inner layer to avoid intermixing of the respective layers while facilitating efficient fabrication.
摘要翻译：一种多层磁记录介质（10）以及制造如上所述的多层磁记录介质的方法。记录介质具有磁性内层（13），磁性颗粒具有特定的矩形比和饱和磁化强度，导致优异的高频输出和改进的重写特性，以及含有铁磁颗粒的磁性外层（14）。制造磁记录介质的方法包括内层的受控部分干燥，以避免各层的混合，同时有利于制造。
