Magnetic head substrate material, magnetic head substrate, head slider, and method of making magnetic head substrate

摘要

A magnetic head substrate used in a head slider includes any of a sintered body, substantially free of Al₂O₃, containing TiCN; a sintered body, substantially free of Al₂O₃, containing TiCON; a sintered body containing TiCN and 10 wt % or less of Al₂O₃; and a sintered body containing TiCON and 10 wt % or less of Al₂O₃. The head slider has a structure in which a thin-film magnetic head is laminated on a support formed from the magnetic head substrate.
