ABSTRACT:
A floating magnetic head of a monolithic type which is arranged in such a manner that a magnetic circuit is constituted by a first magnetic core having an air bearing surface and a second magnetic core to which a wire is wound and being integrally connected with the first core via a magnetic gap, and the backside of the first core is, connected with an adhesive to a holding member of a cantilever holding structure provided for a load arm in such a manner that the longitudinal central axes of the first core and the holding member coincide with each other. The magnetic head has a groove which is formed on the backside of the first core thereof in such a manner that the groove substantially parallels a magnetic gap line, the groove confronts the holding member and the distance between the gap line and an edge line of the groove adjacent to the gap line is 2 to 20% of the entire length of the first and the second cores. Furthermore, no adhesive adheres to the second core.
