ABSTRACT:
A slider is attached to a spring with an epoxy adhesive. The thermal expansion coefficient of the spring is set greater than that of the slider by 10% to 60%. In this range, the deformation of the slider is reduced more effectively than when the thermal expansion coefficients of the slider and the spring are set substantially identical. The slider has a crown. The crown is formed by attaching a face of the slider to a concave surface, forming flat another face of the slider opposing the attached face, and disengaging the slider from the concave surface.
