制限される場合があった。Further, for example, in a magnetic disk device, a servo control system is used to position a magnetic head, and it is necessary to improve positioning accuracy and position at daytime speed. For this purpose, it is necessary to improve the loop gain of the servo mechanism, and it is important to reduce the weight of each structural component and increase its strength to eliminate resonance in the low frequency region. be. However, in the conventional winding method, the 18R plane after winding is as shown in Figure 3, and the wire material is t-shaped, so there is a limit to its strength as a voice coil, and this limits the servo characteristics. There were cases where

の手段は既に広く実用に供されている技術である。Next, FIG. 4 shows a developed view of the sheet forming the voice coil. Each component of the sheet in FIG. 4 is the same as in FIG. 1. The insulating film 7 is made of flexible resin such as polyimide. Further, after adhering a conductor film such as steel onto the conductor pattern 6I/i insulator film 7,
It can be obtained by forming a pattern by photo-etching or the like, or by forming a pattern directly on the 4g edge film by a method such as meshing. These means are technologies that have already been widely put into practical use.

When the sheet is rolled into a cylindrical shape, the pattern connecting portions 9 and 9' match each other in a perfect 9-way pattern, and the land portions A to E and A' to E' each form a book. There are holes in the insulator film in the valley land area, so
A and E and E' are respectively connected by means such as soldering.
