ABSTRACT:
A spherical projection portion for pivotally supporting a magnetic head is protrusively formed in a tongue piece formed in a flexure, and a non-contact portion with the slider are formed on both sides of the projection portion. The backward portion with the projection portion and the non-contact portion as a boundary is formed into a bonding portion. A bonding agent between the bonding portion and the slider is prevented from flowing toward a magnetic conversion element by the projection portion and the non-contact portion. Since the bonding agent is not present in the vicinity of the magnetic conversion element, the magnetic conversion element is not deformed due to the expansion and contraction of the hardened bonding agent. Also, since the bonding area is formed into an appropriate dimension, the protuberance dimension of a crown of the slider is not varied.
