てフィレットを形成して接着の補強を行なっている。[Prior Art] - Conventionally, the slider of a magnetic head was fixed to the suspension by adhering it to the suspension using a non-conductive adhesive such as epoxy resin, as shown in Fig. After the adhesive is bonded, a fillet is formed using the same type of adhesive to strengthen the bond.

波形に影響を与えることがわかった。The magnetic head slider is usually Aj2, 03, TiC, or M.
Materials with good conductivity such as n-Zn ferrite are used, but it has been found that highly conductive materials are susceptible to external noise when their potential is unstable, which affects the readout waveform of the magnetic head. Ta.

まうという欠点がある。In the conventional magnetic head described above, the slider and suspension are bonded and fixed only with a non-conductive adhesive such as epoxy resin, so the potential of the slider becomes unstable and external noise is added to the read waveform of the magnetic head. It has the disadvantage of being

導電性接着剤によって固定することを特徴とする。The magnetic head of the present invention is a magnetic head in which a slider and a suspension are bonded and fixed with an adhesive.
In addition to the adhesive described above, the slider side surface and the suspension are fixed using a conductive adhesive.

いる。Next, an embodiment of the present invention will be described with reference to the drawings. Referring to FIG. 1, a slider 1 is bonded to a gimbal portion of a suspension 2 with a non-conductive adhesive 4, such as an epoxy resin adhesive. Further, a fillet is formed at the position shown in the figure using the conductive adhesive 5 to reinforce the adhesion. As the conductive adhesive 5, one in which fine foils of silver or the like are dispersed in an epoxy resin is commercially available.
上記のような構成によって、スライダとサスペンション
との間が最大数１００Ω程度の抵抗値によって導通され
る。サスペンションは通常アーム（図示せず）にねじあ
るいはカシメ等によって固。With the above configuration, conduction is established between the slider and the suspension with a maximum resistance value of about several hundred ohms. The suspension is usually fixed to the arm (not shown) by screws or caulking.

ているので、結局スライダ１の電位は磁気ディスクドラ
イブの筐体と同電位となって安定するので外来ノイズが
読み出し波形に重畳しにくい構造となる。Since the arm is electrically connected to the casing of the magnetic disk drive, the potential of the slider 1 becomes stable and becomes the same potential as the casing of the magnetic disk drive, resulting in a structure in which external noise is difficult to superimpose on the readout waveform. Become.
本実施例においてフィレットのみに導電性接着剤が使用

強度の十分大きな導電性接着剤があれば、スライダ１と
サスペンション２との接着のために使用する非導電性接
着剤の代わりに導電性接着剤を使用することができる。The reason why the conductive adhesive is used only for the fillet in this example is that the adhesive strength of the conductive adhesive is weaker than the adhesive strength of the epoxy resin-based non-conductive adhesive. That is, a non-conductive adhesive is used to bond and fix the slider and suspension in the original sense, and a conductive adhesive is used at the fillet portion to establish electrical continuity between the slider and the suspension. Therefore, if a conductive adhesive with sufficiently high adhesive strength is available, the conductive adhesive can be used in place of the non-conductive adhesive used to bond the slider 1 and the suspension 2.
本実施例におけるスライダ１の材質はＡｌ１ｚｏｓ・Ｔ
ｉＣ，Ｍｎ−Ｚｎフェライト等、導電性のものである。The material of the slider 1 in this embodiment is Al1zos・T.
It is a conductive material such as iC or Mn-Zn ferrite.
サスペンションの材質もステンレス等、導電性であるこ
とが必要である。The material of the suspension must also be conductive, such as stainless steel.
以上説明したように本発明はスライダとサスペンション
の導通をはかることによってスライダの電位を安定化し
外来ノイズが読み出し波形に重畳しにくくできる効果が
ある。As described above, the present invention has the effect of stabilizing the potential of the slider by establishing conduction between the slider and the suspension, thereby making it difficult for external noise to be superimposed on the readout waveform.
