Protective layer for magnetic recording media |
| abstract |
ABSTRACT OF THE DISCLOSURE A two-layer protective coating covers a metallic thin film magnetic recording medium of a magnetic recording element. The two-layer protective coating comprises a primer layer proximal to the metallic thin film magnetic recording medium. The primer layer comprises an amino functional alkoxy silane and a copolymerisable monomer. The copolymerisable monomer comprises a plurality of vinyl groups. The two-layer protective coating also comprises a lubricant layer distal from the metallic thin film magnetic recording medium. The lubricant layer comprises a functional perfluoropolyether. |
