ABSTRACT:
A magnetic head slider is disclosed, of which a surface in frictional contact with a magnetic recording medium has different shapes adjacent to air stream inlet and outlet ends such that mean gap with respect to the magnetic recording medium is smaller adjacent to the air stream inlet end than adjacent to the air stream outlet end. When performing recording or reproduction, the magnetic recording medium is sucked to be in contact with the magnetic head slider by a negative pressure generated with relative movement of the magnetic recording medium and magnetic head slider.
