ABSTRACT:
A method for efficiently manufacturing a magnetic tape in which damage to the side edges of the tape is prevented so as to prevent problems such as signal dropout. A source tape is provided having a magnetic recording layer formed thereon. The source tape is slivered to produce individual tapes of a final product width. The obverse and reverse surfaces of the individual tapes are then smoothed with a calendaring unit composed of a pair of heated work rolls and a pair of backup pressure rolls, and finally the individual magnetic tapes are wound on long rolls.
