ABSTRACT:
High density information signal recording media of an electrostatic capacitance type, in which an information signal is recorded as geometric variations. The medium consists of a conductive resin composition which comprises a vinyl chloride resin, carbon black particles and a silicone oil lubricant. The carbon black particles are treated with a silicone oil to have the oil coated thereon.
