大する傾向にある。Conventional technology Floating magnetic heads used in fixed magnetic disk drives include a monolithic type magnetic head in which a slider forms part of the magnetic path, and a core chip that forms a closed magnetic path by itself, and this core chip is made of non-magnetic material. A composite type floating magnetic head embedded within the slider parapet 1 of the slider is mainly used. Among these, composite type floating magnetic heads in particular have higher mechanical strength than monolithic types, and even if the core width is narrowed in response to the narrower track widths associated with the recent increase in recording density, the core Since it is embedded in a recess formed in the slider and molded with glass, it has the characteristic that the strength of the core is not lost, and its applications tend to expand.
以下、モノリシックタイプの浮動型磁気ヘッドの従来例
を第4図を参照して説明する。Hereinafter, a conventional example of a monolithic type floating magnetic head will be explained with reference to FIG.

There is. Further, sloped surfaces 5 and 6 are formed at one end portion (air inflow end portion) of the slider pads 2 and 3. Note that 7 and 8 are air outflow ends.

カラスモールドされている。A core chip 9 is made of a magnetic material, and is placed in a slit a provided in the slider 1.
It is molded with crow.
また当然のことながら、前記スリット部1aの幅はこの
スリット部内へのコアチップ9の挿入を容易にするため
にコアチップ9の幅に対して若干広めに形成されている
。Further, as a matter of course, the width of the slit portion 1a is formed to be slightly wider than the width of the core chip 9 in order to facilitate insertion of the core chip 9 into the slit portion.
発明が解決しようとする課題

非常に難しく、作業能率アップの際の一つの障害となっ
ていた。Problems to be Solved by the Invention In the conventional floating magnetic head configured as described above, the core chip 9 must be vertically inserted into the slit portion la, accurately positioned, and then glass molded. This is because if the core chip 9 is fixed in a tilted state inside the sleeve I/portion 1a, the top surface of the core chip may be shaved diagonally during the subsequent polishing of the top surface of the core chip and the top surface of the slider pad. This is because the width of the magnetic gap, ie, the track width, increases. However, this insertion work is extremely difficult and has been an obstacle to improving work efficiency.
また、上記したようにスリットの幅はコアチップの幅よ

より面倒なものにしてしまうという問題がある。Furthermore, as mentioned above, since the width of the slit is wider than the width of the core chip, a gap is formed between the inner wall of the slit and the core depth, as shown in Figure 5. There is a problem in that the glass 10 used for the mold seeps into the coil winding portion 11 through the gap, making the winding work more troublesome.

を固定した。Means for Solving the Problems In order to solve the problem described in item 1, the floating magnetic head of the present invention is provided with a notch extending to the slider pad at one corner of the slider, and is machined into a shape that fits within this notch. The slider, the core chip, and the nonmagnetic plate were fixed with the core chip sandwiched between the nonmagnetic plate and the inner peripheral surface of the notch.

きる。Effect With the above configuration, the core chip can be easily installed into the notch from the side, and the core chip and the inner circumferential surface of the notch, as well as the core depth and the non-magnetic plate, can be brought into close contact with each other, thereby preventing the coil winding portion from being attached. This will prevent the glass from seeping out.
