Problems solved by technology

Therefore, when a voltage that does not exceed a certain threshold is applied, conductivity does not appear, and the conduction between the slider 1 and the cantilever 6 cannot be ensured until the voltage exceeds the threshold.
[0014] Therefore, when the threshold value is larger than the electrostatic breakdown threshold value at which electrostatic breakdown (ESD) occurs in an MR element or the like, conduction between the slider 1 and the cantilever 6 cannot be ensured, and when the slider 1 is charged, due to The charge cannot be bypassed from the conductive resin film 21 to the side of the support member 2. When the slider 1 in this charged state contacts metal or the like, the thin film element 4 such as an MR head may be destroyed by static electricity.

Embodiment 1

[0106] First, as Example 1, a silver-based conductive filler with a particle diameter of about 1 to 5 μm and an outer diameter of 5 nm were prepared as a conductive resin film for the magnetic head having the structure of the aforementioned embodiment. About the material of carbon nanotubes. Carbon nanotubes, for the conductive adhesive weight 100% (the thermosetting resin of epoxy type 16% by weight, the conductive filler of silver type 84% by weight) ) added 10% by weight.

Abstract

A magnetic head includes a slider having a recording and / or reproducing thin film element, and a flexure having an elastically deformable tongue piece, the slider and the flexure being bonded together and electrically connected with a conductive resin film. The conductive resin film includes at least one conductor containing carbon particles, carbon nano-tubes, or a metal nano-powder, a resin adhesive, and a metal conductive filler. The conduction-start voltage of the conductive resin film is set to 1.0 V or less.

Description

technical field [0001] The present invention relates to a suspension-type magnetic head device installed in a hard disk device, etc., and more particularly to an application technology of a magnetic head that conducts a slider and a suspension that supports the slider through a conductive resin. Background technique [0002] Figure 7 It is a partial side view showing the conventional structure of a magnetic head device used in a hard disk device. This magnetic head device is composed of a slider 1 and a support member 2 for supporting it. [0003] The slider 1 is formed of a ceramic material or the like. In addition, on the end surface of the retreat side B of the slider 1, a thin-film element 4 is provided. The thin-film element 4 has an MR head (reader) for detecting a leakage magnetic field of a recording medium such as a hard disk by using a magnetoresistive effect and reading a magnetic signal. head) and an electromagnetic induction head (write head) that forms a pat...
