发明名称 METHOD FOR CONTROLLING MAGNETIC TAPE WINDING POSITION
摘要 PROBLEM TO BE SOLVED: To make it possible to prevent the disturbance in winding of a tape by imparting a temp. difference in the transverse direction of a magnetic tape just prior to taking-up of the magnetic tape to bias the temp. to a lower side and executing orderly winding. SOLUTION: The temp. distribution applied in the transverse direction of the magnetic tape 10 decreases the temp. to be applied at the end of the magnetic tape 10 passing a recessed part 16 having a notch even when the entire part of a heater unit 15 is warmed. When the magnetic tape 10 is wound around a tape reel 14, the temp. distribution is high in the temp. on a lower side 17 in the transverse direction of the tape and is low in the temp. on an upper side 18 in the transverse direction of the tape. The tape tension distribution is higher in the tension of the magnetic tape 10 on the upper side 18 in the transverse direction of the tape and is gentle in the tension on the lower side 17 in the transverse direction of the tape where the temp. is applied. Then, the secure winding is executed on the upper side 18 in the transverse direction of the tape and the air from the lower side 17 in the expanded transverse direction of the tape may be made to escape to the outer side.
