Abstract
An apparatus for correcting curl of a belt-like magnetic recording medium made of a ferromagnetic thin film formed on a flexible substrate, in which the magnetic recording medium fed from a master roll thereof contacts a heating roller so that curl of the magnetic recording medium is corrected. The surface of the heating roller is covered with a material having thermal conductivity lower than that of a material forming the body of the heating roller.
