MAGNETIC RECORDING MEDIUM

摘要

PURPOSE:To improve chroma output and electromagnetic conversion characteristics by forming magnetic layers of the respectively specific uppermost layer and lower layer and forming the lower layer and the uppermost layer of wet-on-wet coating. CONSTITUTION:The 1st magnetic layer 2 and the 2nd magnetic layer 4 are laminated in this order on a nonmagnetic base 1 consisting of polyethylene terephthalate, etc. The uppermost layer 4 contains hexagonal magnetic powder and has 0.1 to 1.0mum thickness. At least one layer of the lower layer 2 contains a binder having a negative functional group and has 500 to 1200Oe coercive force. In addition, the lower layer 2 and the uppermost layer 4 are formed by wet-on-wet coating. The electromagnetic conversion characteristics including the chroma output are improved in this way.
