摘要:
A tape winding method and apparatus in which two sets of magnets disposed at different places around the take-up reel of a magnetic tape apply a magnetic field in the width direction of the tape at one position and in the thickness direction at another position. Thereby, the tape is both radially compressed and evened to one side.
