る。Conventionally, the slider of the magnetic head assembly has been adhered and fixed to the suspension with an electrically non-conductive adhesive such as epoxy resin as shown in FIG. Usually, the slider and the suspension are bonded on the bonding surface, and then a fillet is formed by the same kind of adhesive to reinforce the bonding.

与えることがわかった。The slider of the magnetic head assembly is usually made of Al 2 O 3 · TiC or Mn-Zn.
Although a material having good conductivity such as ferrite is used, it was found that a material having good conductivity is susceptible to external noise when the potential is unstable and affects the read waveform of the magnetic head.

ってしまうという欠点がある。In the conventional magnetic head assembly described above, since the slider and the suspension are adhered and fixed only by the non-conductive adhesive such as epoxy resin, the electric potential of the slider becomes unstable and external noise is generated in the read waveform of the magnetic head. There is a drawback that it will get on.

Including. In another embodiment, the magnetic head assembly of the present invention further includes a non-conductive adhesive that bonds the slider to the suspension, and the bottom surface of the slider is bonded to the suspension by the non-conductive adhesive. The side surface of the slider is bonded to the suspension by the conductive adhesive.

いる。Next, an embodiment of the present invention will be described with reference to the drawings. Referring to FIG. 1, the slider 1 is bonded to the gimbal portion of the suspension 2 with a non-conductive adhesive 4 such as an epoxy resin adhesive. Further, a fillet is formed at the position shown by the conductive adhesive 5 to reinforce the adhesion. As the conductive adhesive 5, an epoxy resin in which fine foil such as silver is dispersed is commercially available.

構造となる。With the above configuration, the slider and the suspension are electrically connected by a resistance value of about several hundreds Ω at the maximum. The suspension is usually fixed to an arm (not shown) by screws or caulking, and the arm is electrically connected to the housing of the magnetic disk drive.
Since the potential is stable at the same potential as that of the magnetic disk drive housing, external noise is less likely to be superimposed on the read waveform.

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 embodiment is that the adhesive strength of the conductive adhesive is weaker than that of the epoxy resin-based non-conductive adhesive. That is, a non-conductive adhesive is used to bond and fix the slider and the suspension in the original sense, and a conductive adhesive is used for the fillet portion to establish conduction between the slider and the suspension. Therefore, if there is a conductive adhesive having a sufficiently large adhesive strength, the conductive adhesive can be used in place of the non-conductive adhesive used for bonding the slider 1 and the suspension 2.
