Magnetic head.

摘要

In a ring-shaped magnetic head in a sandwich structure of magnetic cores with nonmagnetic substrates, by achieving electric conductance between a pair of opposing magnetic cores, electrostatic noise generated due to sliding of the recording medium can be prevented without grounding the cores themselves. If mounted on an insulating head base, conductor for grounding is not needed. Besides, the head chip can be manufactured in a few manufacturing steps by the processing to achieve conductance between magnetic cores in a state of core block composed of plural head chips when manufacturing a magnetic head.
