A COIL FOR MAGNETIC FIELD GENERATION Abstract of the Disclosure An improved coil for magnetic field generation in bubble memory devices. A stripe line coil pattern having varying widths of conductors is etched from a conductive film supported on a polyamide film. The stripe line layer is wrapped around a coil form and the outer ends of the conductors are electrically connected in an offset fashion to form a field coil having a single closed loop. The stripe line coil is arranged in a multiple layer structure having the conductors with varying widths aligned in series along the layer direction rather than in parallel, thereby providing improved magnetic field uniformity and minimizing high frequency loss in a uniform, easily wound coil configuration. A stripe line coil having reduced resistance and correspondingly minimized power loss is achieved by substantially increasing the ratio of stripe line conductor area to insulation area. This is accomplished by forming the coil from a single sided stripe line with a double thick conductor film, in one preferred embodiment of the invention, or, from a double sided stripe line, in another preferred embodiment.
