SUBSTRATE FOR THIN FILM MAGNETIC HEAD, MAGNETIC HEAD SLIDER, AND HARD DISK DRIVE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an AlTiC based substrate suitable for a substrate for a thin film magnetic head.SOLUTION: An AlO-Tic based substrate for a thin film magnetic head includes an AlOphase and a TiC phase. A lattice constant of a c axis of the AlOphase is 12.992 angstroms or more and 12.998 angstroms or less, and a lattice constant of the TiC phase is 4.297 angstroms or more and 4.315 angstroms or less.SELECTED DRAWING: Figure 4
