Abstract

PURPOSE:To eliminate the deterioration in the physical properties of the resin due to the environmental change of a lubricant and to lower a coefficient of dynamic friction to a magnetic recording medium by including a specific weight % of a filler of a specific particle size in the filling resin for storing and fixing a magnetic core in a shield case. CONSTITUTION:The lubricant is not used in the filling resin 30 for fixing the magnetic core 11 in a shield case 21. Then, in order to lower the coefficient of dynamic friction, the particle size of the filler is defined to be 1-15mum and it is included by 50-70wt.% to 100wt.% of the resin. As for the filler, SiO2 preferable and an inorganic material such as CaCO3, glass beads, talc, molybdenum disulfide may be used. When the particle size of the filler is defined to be particulate below 1mum, a mixture to the resin is not effectively executed but when it is above 15mum, the suppressing effect of the coefficient of dynamic friction is lowered. When the quantity of addition is set to above 70wt.%, a proper mixing state to the resin cannot be maintained.
