ABSTRACT:
A magnetic head which can fly over a surface of a magnetic recording medium comprises a main body fitted into a supporting arm, rail surfaces formed in the main body to serve pneumatic bearings, and projections formed on the rail surfaces and having surfaces opposing a magnetic recording medium. The projections have larger surface roughness than that of the magnetic recording medium, whereby wear-out rate of the projections provided on the magnetic head can be reduced and also the projections can be firmly brought into contact with the surface of the magnetic recording medium.
