25/13 MAGNETIC TAPE COPYING METHOD AND APPARATUS In magnetic tape copying method and apparatus wherein a slave tape heated to a temperature near the Curie point and a master tape having a signal recorded thereon are put together with their magnetic surfaces in contact with each other and then cooled, an improvement of reheating the slave tape, after the completion of the transfer, under a smaller tension than that applied during the transfer at a temperature lower than the Curie point to prevent the occurence of skew distortion on a reproduced picture due to deformation with the passage of time of the slave tape.
