Magnetic recording medium

摘要

The present invention aims to provide a magnetic recording medium for digital recording/reproducing systems having a small bit area, i.e. a short recording wavelength and a narrow track width, which is a particulate magnetic recording medium showing good electromagnetic characteristics.A magnetic recording medium comprising a nonmagnetic layer containing a nonmagnetic powder and a binder and a magnetic layer containing a ferromagnetic powder and a binder provided in this order on a nonmagnetic substrate wherein said magnetic layer has an average thickness of 0.01-0.1 mum and the ratio of the area of magnetic recording defects generated upon magnetic development after recording at the shortest recording wavelength to the total magnetic recording area is 0.2-20%.
