切欠溝内に封着ガラス材料を充填したことを特徴
とするサイドコアを有する磁気ヘツド。 (2) 実用新案登録請求の範囲第１項において、
センタコアはセンダスト材からなつているサイド
コアを有する磁気ヘツド。 (3) 実用新案登録請求の範囲第１項または第２
項において、サイドコアは、本体が強磁性フエラ
イト材からなり、磁気テープ摺接面が非磁性材料
からなつているサイドコアを有する磁気ヘツド。[Claims for Utility Model Registration] (1) In a magnetic head formed by side cores joined to both sides of a center core having a magnetic gap, the center core is provided with notched grooves located at both ends of the magnetic gap to regulate track width. What is claimed is: 1. A magnetic head having a side core, the side core having a notched groove filled with a sealing glass material. (2) In paragraph 1 of the claims for utility model registration,
A magnetic head with a center core and side cores made of Sendust material. (3) Scope of claims for utility model registration, paragraph 1 or 2
2. A magnetic head according to item 1, wherein the side core has a main body made of a ferromagnetic ferrite material and a magnetic tape sliding surface made of a non-magnetic material.
