ABSTRACT:
A cleaning medium for magnetic recording devices comprises a non-magnetic substrate and a lower coating layer, which is overlaid upon the non-magnetic substrate and primarily contains a binder and non-magnetic inorganic particles dispersed in the binder. The cleaning medium also comprises a cleaning layer, which is overlaid upon the lower coating layer and contains a binder and inorganic particles dispersed in the binder, the inorganic particles at least containing ferromagnetic particles. The thickness of the cleaning layer falls within the range of 0.05 .mu.m to 1.0 .mu.m, and the squareness ratio of the cleaning layer falls within the range of 0.6 to 0.98. The cleaning medium yields little wear of magnetic heads, has good cleaning characteristics, and is capable of trueing up the shape of an end of a cleaned magnetic head into a sharp shape, such that the compatibility of the magnetic head with both of a metal evaporated tape and a metal powder tape in coming into close and uniform contact with the tapes may be kept good.
