Magnetic head having cut-out portions for different recording density head cores

1. Field of the Invention The magnetic head is structured such that a high-density recording head core and a normal recording head core are assembled integrally into the same slider In the same side surface of the slider there are formed a first cut-out portion into which the high-density recording head core can be inserted, and a second cut-out portion into which the normal recording head core can be inserted. The two cut-out portions and are formed in such a manner that they respectively extend in the rotational direction (A direction) of a magnetic disc. The two kinds of head cores and having different recording densities are respectively inserted into and the core hold portions and of the cut-out portions and opened up in the same side surface of the slider and are then fixed thereto with adhesives and The two head cores and are assembled into the cut-out portions and from the same direction and are then fixed to the hold portions and in such a manner that they are arranged in parallel to each other.
