MAGNETIC RECORDING MEDIUM & THE PRODUCING METHOD

摘要

The magnetic recording medium of high density is manufactured by coating a paint to be dispersed with magnetic powder on the non-magnetic substrate. In the process, 3-glycidyloxypropyl methyldiethoxy silane of formula (I) as a coupling agent is coated with 0.05-1 micrometer before coating process of the magnetic paint. The magnetic recording disk is manufactured with the obtd. magnetic recording medium. The magnetic recording medium has good record regenerating property.
