Problems solved by technology

In this way, under the action of the air layer, the influence of the taper is reduced, and when the diameter is large, it is difficult to make the tape develop a good winding habit.

no. 1 Embodiment approach

[0050] Below, refer to Figure 1- Image 6 , the tape winding method according to the first embodiment will be described.

[0051] Among the drawings referred to, FIG. 1 is a perspective view showing the overall structure of a winding device used in the tape winding method according to the first embodiment. figure 2 It is a perspective view showing the overall structure of the heat treatment apparatus used in the tape winding method according to the first embodiment. image 3 (a) is a partial cross-sectional view schematically showing the winding state in the initial stage of winding in the X-X cross section shown in FIG. 1 . image 3 (b) is schematically indicated at image 3 (a) Thereafter, a partial cross-sectional view of the winding state in the mid-winding stage in which winding is continued. Figure 4 (a) is schematically indicated at image 3 (b) Partial front view of the tension generated by the magnetic tape in the mid-winding stage shown. Figure 4 (b) is a part...

no. 2 Embodiment approach

[0109] Below, refer to the appropriate Figure 7 and Figure 8 , and the tape winding method according to the second embodiment will be described.

[0110] In the referenced figure, Figure 7 It is a perspective view showing the overall structure of the winding device used in the tape winding method according to the second embodiment. Figure 8 (a) is a schematic representation Figure 7 In the Z-Z section shown, a partial cross-sectional view of the winding state in the initial stage of winding. Figure 8 (b) is a partial cross-sectional view schematically showing the winding state in the middle of winding in which winding is continued.

[0111] The tape winding method according to the second embodiment differs from the tape winding method according to the first embodiment only in the winding step. More specifically, depending on the structure of the winding device, the method of winding the magnetic tape MT onto the shaft 2 is also different. In the first embodiment, w...

no. 3 Embodiment approach

[0123]Next, referring to FIG. 9 , the tape winding method according to the third embodiment will be described.

[0124] Of the figures referred to, FIG. 9( a ) is a front view showing the overall structure of a winding device used in the tape winding method according to the third embodiment, and schematically showing the winding state in the initial stage of winding. FIG. 9( b ) is a front view schematically showing a winding state in a later stage of winding in which winding is continued after FIG. 9( a ).

[0125] The tape winding method according to the third embodiment is different from the tape winding method according to the first embodiment only in the winding step. More specifically, depending on the structure of the winding device, the method of winding the magnetic tape MT onto the shaft 2 is also different. In the third embodiment, instead of using the coil outer peripheral surface pressing member 10 according to the first embodiment, a winding guide 51 having a gu...

Abstract

A tape winding method of the present invention comprises a winding process for winding tape on a periphery of a hub by rotating the hub so that one end surface of a wound roll, which consists of the tape having a base film and being wound, becomes concave; and a heating treatment process for performing a heating treatment for the wound roll within a predetermined temperature range just under a glass transition temperature of the base film.

Description

technical field [0001] The invention relates to a winding method of a magnetic tape. Background technique [0002] Magnetic recording tapes (hereinafter referred to as "tapes") have become thinner and smoother along with higher recording density. However, when such a tape is wound onto a tape reel with a tape winding machine or a tape drive, it is prone to uneven tape winding, especially when winding at a high speed, serious tape winding unevenness often occurs. . [0003] This unevenly wound tape on the tape reel is likely to cause edge damage during the handling process. During storage, it will also cause the tape to develop a bad winding habit, resulting in a decrease in the walking accuracy and servo failure in the tape drive. Track exceptions and other issues. [0004] Therefore, manufacturing a magnetic tape that can ensure the quality of the winding posture at the time of shipment and that is less prone to uneven winding when running in the tape drive has become an...
