ABSTRACT:
The present invention provides; a magnetic disk recorder comprising (i) magnetic disks having magnetic recording media, (ii) thin-film magnetic heads for recording information in the recording media and reproducing information therefrom, and (iii) a carriage for moving the magnetic heads to intended positions, the recorder being wherein the thin-film magnetic heads are formed on sliders and these sliders comprise sintered bodies containing a non-magnetic metal oxide of spinel structure and harder ceramic particles than the metal oxide which are dispersed in the metal oxide; a sintered body useful particularly as a material for the magnetic head slider, a method for making the sintered body, and a magnetic head and a magnetic head slider, for recording and reproducing information, which are made by using the sintered body.
