Abstract:
At least one spiraled semi-circular shaped coil is printed on each surface of a wafer. The coil on a first surface of the wafer is arranged in such a manner that it is rotated 90 degrees with respect to the coil on a second surface thereof. In one embodiment, two such printed coils are symmetrically provided on each surface of the wafer, and the pattern of the printed coils on the first surface is arranged to be rotated 90 degrees with respect to the pattern of the printed coils on the second surface thereof. The spiraling directions of the coils on the same surface are inverse or opposite each other. The inner terminals of the coils on each surface are connected and an output is taken out from the outer terminals thereof, or vice versa. A printed coil is employed, for example, in a moving coil type pick-up cartridge.
