Magnetic head which minimizes the effect of minute variations in the head gap

摘要

The magnetic head of the present invention has a core thickness set up in accordance with the range of the permeability drop starting frequency of the core material which is determined to reduce the influence imparted to the reproducing frequency characteristic of the head by any minute variation in the technique of making the head gap. The core thickness of the magnetic head may be attained by using a smaller number of superposed layers to form the core than in a conventional magnetic head, and in some cases, a single layer of the core may be used to provide the track width.
