Abstract
A tape for a magnetic tape recorder or the like is taken up while the barometric pressure around the part of the take-up reel where the tape is being wound is kept below atmospheric pressure. The tape can thus be taken up in a stable manner at a high speed, by eliminating the tape floating force which is the basic cause of irregular take-up phenomenon.
