Abstract:
There is obtained a substrate for thin film magnetic head having extremely excellent heat radiation and insulation properties and extremely flat surface. On a substrate comprising ceramics or single crystal member, a substrate for thin film magnetic head is constituted with a high thermal conductive insulating film having a thickness in the range of 10-1500 .ANG., thermal conductivity at room temperature higher than 45 W/m.multidot.K, and volume inherent resistance higher than 10.sup.8 .OMEGA..multidot.cm.
