ABSTRACT:
The present invention relates to non-magnetic ceramic substrate material for magnetic head having similar thermal expansivity to the metal magnetic thin film, abrasion resistance during contact traveling of the magnetic tape and good processability and thus increasing lifetime by preventing exfoliation and crack of the magnetic thin film. The material comprises 10-35 mol % of CaO, 10-40 mol % of TiO.sub.2, 10-60 mol % of NiO and 10-50 mol % of CoO.
