2. Description of the Related Art Rotating heads used in VTRs, DATs, etc. are consumables that wear out over time. Therefore, it is necessary to design the product on the assumption that the rotating head will be replaced. Furthermore, it is convenient for the rotary head to be easily separated from the circuit block in terms of product manufacturing. For this reason, the connection between the rotating head and the circuit block requires
It is common to use connectors that do not require special tools.

On the other hand, the signal output from the rotary head is output to the RF amplifier of the circuit block through a signal output line. This signal is an RF signal obtained by converting the magnetic signal on the magnetic tape into an electric signal, and is weak at 10 to several tens of microvolts. Furthermore, since the frequency band of this RF signal extends to several megahertz, it is necessary to fully consider S/N deterioration and frequency characteristic deterioration when designing the RF signal transmission path and amplifier circuit.

Examples of such output wires include coaxial wires, shielded wires, and flexible printed circuit boards (hereinafter referred to as FPC boards). Among these, an FPC board can be said to be the most suitable output wire material in consideration of the workability of the connector part, wire processability, parts cost, etc. In addition,
This FPC board is made by closely molding a wiring pattern of copper foil or the like on the surface of a flexible base film, and then covering the board with an insulating film such as a resin film. Figure 3 shows the F connected to the rotating head.
