Since the electric potential of the slider is unstable such as O 3 .Tic, the read signal of the magnetic head is easily affected by external noise when the potential of the slider is unstable. To solve this problem, for example, as described in Japanese Patent Application Laid-Open No. 2-244419, in addition to a non-conductive adhesive for fixing the slider and the suspension, an epoxy-based adhesive that establishes conduction between the slider and the suspension is used. Use a conductive adhesive.
