ABSTRACT:
A floating magnetic head has two or more slider portions with floating surfaces formed thereon generally in parallel with a plane on which a magnetic disk rotates. The magnetic head body has grooves formed between the adjacent slider portions in a facing relation with a recording surface of the magnetic disk. Water removing members are formed in at least a portion of the grooves and the floating surfaces of the slider portions for removing water formed on the magnetic disk surface by electrolyzing the water. The water removing member comprises a cathode electrode, a proton-conductive solid laminated on the cathode electrode, an anode electrode laminated on the proton-conductive solid and facing the surface of the magnetic disk. Water films formed in the gaps between the surface of the magnetic disk and the floating surfaces of the slider portions are removed by electrolysis effected by the water removing members.
