A magnetic head reduces a slant of a magnetic head chip in comparison with a conventional case. The magnetic head is produced by a manufacturing method. A ridge on a back surface side of a magnetic chip is brought into contact with a chip attachment surface of a chip attachment base. A height of the magnetic head chip is adjusted by using the ridge as a fulcrum.

Magnetic head and method for producing the same

A magnetic head capable of preventing erosion of the magnetic metal film despite the absence of a protective film and preventing a decrease in the playback output due to decrease of the track width while preventing cracking from being initiated and developed in the ferrite substrate is disclosed. The magnetic head is prepared by forming magnetic core half blocks and by bonding the core half blocks via gap bonding, each of the magnetic core half blocks being previously formed by stacking a ferrite substrate on another ferrite substrate having magnetic metal films via glass films and forming track width adjustment grooves. The glass transition temperature Tg of the glass employed for stacking the ferrite substrates is set so as to be higher than the glass yield point Tc of the fusion glass.
