摘要：
A magnetic head comprises a pole layer and first and second coils located in regions sandwiching the pole layer. Each of the two coils is flat-whorl-shaped. The first coil incorporates an inner connecting portion and an outer connecting portion opposite to the inner connecting portion. The second coil also incorporates an inner connecting portion and an outer connecting portion opposite to the inner connecting portion. The inner connecting portion of the first coil is electrically connected to the inner connecting portion of the second coil. The outer connecting portion of the first coil is electrically connected to the outer connecting portion of the second coil, too. In such a manner the two coils are electrically connected to each other in parallel.
