Abstract
The magnetic head disclosed has a slider which comprises a running surface where contact-sliding with respect to a magnetic recording medium occurs, and a polycrystalline silicon film which is provided on at least a portion of said running surface. The polycrystalline silicon film has a thickness of 3 to 10 nm. The running surface is formed of Al.sub.2 O.sub.3.TiC ceramic or silicon. This arrangement is effective in preventing an attraction phenomenon between the head and medium, reducing a frictional coefficient and suppressing damage to the medium.
