A magnetic recording medium wind-up method for winding up a long strip-like magnetic recording medium into a coil around a core comprises the steps of pressing the wound-up portion of the magnetic recording medium toward the core with a predetermined pressure while the magnetic recording medium is being wound up around the core. A predetermined length of the magnetic recording medium is wetted, which length will be wound up around the core immediately before the core is fully loaded with the magnetic recording medium, immediately before the predetermined length of the magnetic recording medium is wound up.
