MAGNETIC RECORDING MEDIUM

摘要

PURPOSE:To obtain a high density magnetic recording medium which is free from troubles due to the electrification by providing a semiconductor layer between a substrate and a magnetic layer. CONSTITUTION:A semiconductor layer is provided between a flexible and insulated substrate and a magnetic layer for a magnetic recording medium containing the magnetic layer consisting mainly of hexagonal ferrite fine particles and a binder. Thus the electrification is avoided on the surface of the magnetic layer while maintaining the high density recording properties. Furthermore a sticking phenomenon due to the electrification on the rear side of the substrate can also be eliminated for the recording medium. The electrification preventing effect is especially high with the >=5mum thickness of the magnetic layer. The electrical conductivity of the semiconductor layer is preferably set at 1X10<8>-1X10<11>OMEGA in terms of the surface resistance value.
