Magnetic recording medium
摘要:
There is disclosed a magnetic recording medium comprising a support; a conductive layer, containing a conductive carbon, formed on either surface or both the surfaces of the support; and a magnetic layer formed on the conductive layer and containing at least a magnetic powder, a lubricant, a binder resin and 0.3 to 3 parts by weight of a conductive carbon based on 100 parts by weight of the magnetic powder.The magnetic recording medium according to this invention can maintain magnetic properties and has the excellent durability and runnabilities. In particular, the magnetic recording media of this invention can be usefully utilized for the magnetic recording as the media for floppy disks, computer tapes, highly accurate magnetic recording tapes and for high definition VTR the like which will be used very often repeatedly and will be exposed to severe circumstances.
