ABSTRACT:
A magnetic record for use in magnetic disc or drum recording playback systems is provided with at least a solid lubricant thin-film outer surface. The lubricant is applied to the disc surface by rubbing under pressure to obtain a uniform lubricant layer of a thickness less than the particle diameter of the original lubricant. By properly selecting the material underlying the surface layer, the lubricant can be made to strongly adhere thereto such that an excellent lubricating effect is obtained between the record and the recording/playback head.
