【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、磁気ディスク装置用の複合型磁気ヘッドに関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a composite magnetic head for a magnetic disk device.
従来の複合を磁気ヘッドのコアチップ１は、スライダー
６にガラス３融着されてい【、第２図のようにコアチッ
プ１と、ガラス３が同一平面上で接着していた。The core chip 1 of a conventional composite magnetic head has a glass 3 fused to a slider 6 [as shown in FIG. 2, the core chip 1 and the glass 3 are adhered on the same plane.
しかし、前述の従来の技術では、ガラスの透明度や屈折
により、ギャップデプスが測りにくいとい５問題点を有
する。However, the above-mentioned conventional technology has five problems in that it is difficult to measure the gap depth due to the transparency and refraction of the glass.
そこで本発明は、このような問題点を解決するもので、
ギャップデプスの計測を容易にして検査の効率を上げる
ところにある。Therefore, the present invention aims to solve these problems.
The purpose is to make it easier to measure the gap depth and increase inspection efficiency.
本発明の複合型磁気ヘッドは、コアチップをスライダに
ガラス融着により埋め込まれてなる複合型磁気ヘッドに
おいて、コアチップのギャップ付近の外側のガラス部分
の一部分を削りたことを特徴とする。A composite magnetic head of the present invention is a composite magnetic head in which a core chip is embedded in a slider by glass fusing, and is characterized in that a portion of the outer glass portion near the gap of the core chip is shaved off.

時のように傾け【ある。第５図はそれを真上から見た図
で、第６図は、そのギャップ５付近の拡大図である。こ
の傾きからギャップデプス７の真の値を計算する。If a part of the glass 3 outside the gap 5 of the core chip 1 is cut and tilted as shown in FIG. 1, the gap depth 7 can be observed without looking through the glass 3. FIG. 4 is a front view of the vicinity of the core chip 1, which is tilted as in the case of gap depth measurement. FIG. 5 is a view of it viewed from directly above, and FIG. 6 is an enlarged view of the vicinity of the gap 5. The true value of the gap depth 7 is calculated from this slope.
以上述べたように本発明によれば、ギャップデプス７を

イダ６の傾きだけから簡単な計算で正確な値を導くこと
ができる。As described above, according to the present invention, when measuring the gap depth 7, it can be measured without looking through the glass, so it is possible to measure the gap depth 7 from only the inclination of the slider 6 at the time of measurement, regardless of the bubbles, transparency, refractive index, etc. of the glass. Accurate values can be derived with simple calculations.
