Abstract

PURPOSE: To obtain a magnetic disk which is inexpensive and lightweight and has small thermal expansion by forming a substrate of a mixture composed of a synthetic resin and inorg. filler.
CONSTITUTION: The substrate is formed of a mixture composed of 60W90wt% synthetic resin and 40W10wt% inorg. filler. The effect of decreasing the thermal expansion is small if the content of the filler is <10% and there is a problem in terms of the mechanical strength when the content thereof exceeds 40%. The preferable content is a 30W15% range and the conductive filler is preferably used at ≥10% thereof in the case of the rendering electrical conductivity to the substrate.
