and 14 may provide enough structural integrity in themselves so that the support bar 24 may not be required fig2 illustrates the end view of the same composite magnetic head of fig1 the read write ferrite core 10 is again illustrated central in the construction of the composite magnetic head on either side of the read write ferrite core 10 i e in this case the near side and the far side of the read write ferrite core 10 are positioned erase ferrite cores 12 and 14 since this is an end view and the erase ferrite cores 12 and 14 are positioned one exactly in front of and behind the other the view shows only one of the two erase ferrite cores 12 and 14 note that the read write ferrite core 10 is constructed substantially in a u shape with the effective gap 26 located at the top in the fig2 or at the base of the u shape notice that the u shape of the read write ferrite core 10 consists of a central leg 42 and an outer leg 48 extending to the right in fig2 and that the erase ferrite cores 12 and 14 also consist substantially of a u shape containing a central leg 46 and an outer leg 48 extending to the left in fig2 or the opposite side from the direction in which the outer leg of the read write ferrite core 10 extends the erase ferrite cores 12 and 14 also have an.
