PURPOSE:To obtain a thin-film head which has an improved reproduction output, etc., by providing a groove for winding to at least either of a couple of nonmagnetic substrates, forming a magnetic thin film which increases in width from a pole piece part to a winding part, and beveling the edge of the magnetic film and the edge of the groove part. CONSTITUTION:A hollow part 11 and the groove 10 for the winding are formed in at least either of nonmagnetic substrates 2 and 2', i.e. substrate 2 and magnetic thin films 4 and 4' are formed on the opposite surfaces of the substrates 2 and 2' so that the width W increases from pole piece parts 13 and 13' to the winding part and the width W' of the winding part is >=5 times as large as the width W of the pole piece part 13. Further, the edge 4a of the film 4 of the winding part and the edge 10b of the groove 10 are beveled; the winding 8 contacts with the wall of the groove 10 and the film 4, the inductance of the winding 8 is minimized, and the generation of a noise at the edge parts is prevented. Thus, the winding 8 is turned many times easily to obtain the head which has the improved reproduction output and superior wear resistance, mechanical strength, high frequency characteristics, etc. |
