Abstract

A thin film magnetic head slider is formed of a sintered material made of a mixture of AlN and TiN. The ratio of volume % AlN to TiN in the mixture is in the range of 50:50 to 99:1. The thin film magnetic head slider has improved lubricant property as shown by its high contact-start-stop (C.S.S.) life.
