ABSTRACT:
In a magnetic tape wind-up system for winding up a magnetic tape into a roll shape around a wind-up core, a feed direction of the magnetic tape to a tape roll, which is formed by winding up of a preceding portion of the magnetic tape, is controlled by a position control roller before the magnetic tape arrives at the tape roll. The position of the magnetic tape in the tape width direction is controlled by an edge control roller at a position where the magnetic tape arrives at the tape roll. Air between turns of the magnetic tape in the tape roll is discharged by pushing the magnetic tape against the tape roll by use of a push roller while the magnetic tape is present at the outermost circumference of the tape roll.
