    摘要： A non-magnetic substrate used for a magnetic head comprising a pair of non-magnetic substrates, and a magnetic layer structure sandwiched between the pair of non-magnetic substrates. The magnetic layer structure is comprised, of alternately laminated magnetic layers and intermediate insulating layers. The invention discloses for the substrate material a composition expressed by Zn.sub.x M.sub.y Co.sub.2-x-y O.sub.2, with the proviso that M is Mn or Ni, 0.ltoreq.x.ltoreq.0.4, 0.4.ltoreq.y.ltoreq.1.0, 0.8.ltoreq.x+y.ltoreq.1.0, or Co.sub.x Ni.sub.2-x O.sub.2, with the proviso that 0.2.ltoreq.x .ltoreq.1.8, and having a rock-salt structure.
