決め精度を向上させる事であ□る。The feature of this invention is that the VCM coil is
To install the coil, in the head positioning mechanism that is fixed to the plate, the VCM coil is sandwiched between the VCM coil fixed foot plates from both sides, glued, and screwed, thereby reducing the impact force during access operation or the temperature of the coil. This is to prevent the adhesive from peeling off due to the decrease in adhesive strength due to the rise, and to prevent the accompanying mechanical vibration, thereby improving the highly reliable positioning accuracy of the magnetic head.
