Magnetkopf und Verfahren zur Herstellung desselben

摘要

A magnetic head (1) includes two substrates (7) which are provided with magnetic cores (3) of magnetic film on their surface and are bonded on a plane so that a magnetic gap (5) is defined between the magnetic cores, an edge part of the magnetic cores with the magnetic gap (5) facing to a track of a recording medium being thinned from opposite sides thereof, and the magnetic cores (3) in any other part being thicker than the edge part. In a gap facing plane where a pair of the magnetic cores (3) join together, the magnetic cores are registered with each other so that they can be opposed to each other in a larger width in the back gap than in the front gap. As a result, even if a tolerance of a process in manufacturing is considerably loosened, a magnetic head (1) with high core efficiency can be obtained with a high yield.
