MAGNETIC RECORDING MEDIUM

摘要

PURPOSE:To obtain a magnetic recording medium which is capable of making high-density recording and has a good traveling property and durability by specifying the deformation rate (in the direction perpendicular to the film plane from the magnetic layer side) of the final coated film formed by a magnetic coating compd. to <=1X10<-2>mum/mgf/mum<2>. CONSTITUTION:The deformation rate (obtd. by applying a load in the direction perpendicular to the film plane from the magnetic layer side) of the final coated film formed by the magnetic coating compd. is <=1X10<-2>mum/mgf/mum<2>, more preferably 1X10<-2>mum/mgf/mum<2>-1X10<6>mum/mgf/mum<2>. The amt. of the deformation is smaller than the conventional magnetic recording medium when a comparison is made with the same friction force. The change in the area degree of the sliding surface during the sliding period is much smaller. The impairment of the durability and the traveling properly is thereby obviated even if the area degree of the magnetic recording medium is improved for the purpose of increasing the recording density of the magnetic recording medium.
