摘要： PURPOSE:To apply control force in the breadthwise direction of tape with an air flow at the time of tape winding and to prevent the magnetic tape from being thrown into winding disorber by providing recessed grooves for air flowing-out radially from a winding core of the tape at the inner surface of a flange. CONSTITUTION:In a tape reel 1, the upper flange 4 is formed on the upper end face of a tape winding core 3 integrally molded with the lower flange 2. Five linear recessed grooves 5 for air flowing out radially extending toward the outer periphery are provided on the inside surface of the flange 4 at regular intervals, and also through-holes 6 for air inflow communicating to the inner end part at the side of winding core 3 of the groves 5 for air flowing out are bored on the flange 4. By the constitution in such a manner, the air flows in from the through-holes 6 and goes through the grooves 5 by the centrifugal force at the time when the tape is taken up at high speed around the tape reel 1, then the air stream is generated in the outer peripheral direction of the flange from the winding core 3, and the control force is applied in the breadthwise direction of tape, thereby the tape is prevented from being thrown into winding disorbed.

摘要： PURPOSE:To prevent the disturbance in winding of a tape by providing recessed grooves for outflow of air radially from a tape winding core toward the outer periphery of a flange and having through-holes for inflow of the air communicating in the recessed grooves. CONSTITUTION:The tape reel 1 is constituted by fixing the upper flange 4 to the top end face of the tape winding core 3 integrally formed with the lower flange 2. The recessed grooves 5 for outflow of the air extending radially from the winding core 3 to the part near the outer periphery of the flange 4 are provided at equal spacings on the inside surface of the flange 4. Through-holes 6 for inflow of the air communicating with the inside end on the winding core 3 side of the recessed grooves 5 are bored in the flange 4. As a result, the air introduced from the through-holes 6 into the inner side of the flange 4 when the tape 8 is taken up at a high speed. The flow of the air is then generated in the outer peripheral direction of the flange 4 from the winding core 3 through the recessed grooves 5. Then, the disturbance in the winding of the tape 8 is prevented even if the air is intruded between the tapes 8.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic tape that can meet the requirement for high-density recording and reduce damages to the tape by suppressing the meandering run of the tape in actual use.
SOLUTION: By running a 12.65mm wide magnetic tape 1 along the reference run surface S and keeping the tape edge 4a at the reference position T applying a tape tension of 0.65N to 0.75N, the tape is inclined by 1.5 degree that is β by an inclined guide 5 to the reference run surface S and wound around the inclined guide 5 by 60 degrees that is α. A measuring instrument 6 positioned near the inclined guide 5 measures the misregistration H of the tape which is the distance from the reference position T to the lower tape edge 4a to obtain the amplitude of the curve of the tape edge 4a. The amplitude of the curve measured in this condition shows that the magnetic tape 1 runs with a displacement of 0μm to 30μm all through its length.

摘要： PURPOSE:To prevent the winding distortion of a tape to be wound around a tape reel by thinning the peripheral surface of a reel shaft from the upper end to the lower end at the inclining angle of 3 to 8 minutes. CONSTITUTION:A tape reel 1 is constituted by fixing a flange 3 to the upper and lower end parts on the outer peripheral wall of a reel shaft 2, and a peripheral surface 21 of the reel shaft 2 is gradually thinned from the upper end to the lower end at an inclining angle theta in the range of 3 to 8 minutes. When a tape 4 such as a video tape or the like is wound around such a tape reel 1, the tape 4 is taken up on the lower side, where the slope is made low, along the slope of the reel shaft peripheral surface 21 and even when there is inclination caused by the slight nonuniformity of thickness in the tape 4 itself, the tape is regularly taken up on the lower side by canceling the thickness nonuniformity of this tape 4 itself. Thus, there is no distortion in the tape 4 to be wound around the tape reel 1 and the tape 4 is always fed out from a prescribed position with the satisfactory winding posture of the tape 4.
