Abstract
In a magnetic head for writing/reading a magnetic disk comprising sliders (15, 16) having sliding surfaces which are brought into contact with a surface of the magnetic disk so as to slide relatively to the magnetic disk and a spacer (20) for adjusting height of the sliders (15, 16), each of the sliders (15, 16) is formed from a nonmagnetic material consisting of calcium titanate, and the spacer (20) is formed from a ferrite-group magnetic material, the ferrite-group magnetic material being selected to have substantially the same coefficient of thermal expansion as that of the nonmagnetic material.
