The first cutting groove 4 and the second cutting groove 3 are formed and connected to each other, and the transverse grooves 6a and 6b are provided. Then the first groove 1
At 0a, a plurality of core assemblies 2 are arranged with a space between the first cutting groove 4 and the second cutting groove 3. At this time, the reference surface 7 on the medium facing surface side of the core assembly 2 is partially exposed by the transverse groove 6. On the other hand, the R surface is always formed during the groove processing. Therefore, the first groove 10a for arranging the core assembly 2 also includes the R portion 15
Is formed, and the reference surface 7 on the medium facing surface side of the core assembly 2 is formed.
Does not come into close contact with the lower surface in the first groove 10a, the position varies, and even if the polishing with a constant polishing dimension 5 is performed, the gap depth obtaining accuracy becomes unstable.
