PURPOSE:To obtain an excellent high-speed recording wire hawing an improved abrasion resistance, by forming a wire body from molybdenum and forming an inorganic film having high hardness onto the outer circumference at the tip for striking a recording medium in the wire body. CONSTITUTION:A wire body 2 is formed entirely from pure molybdenum. A titanium nitride film 3 of 1-10mum thick is formed as an inorganic film having high hardness over the outer circumferential face 2b at the tip portion of the wire body 2 thus composing a wire 1. Since said wire 1 has the wire body 2 formed from molybdenum exhibiting most excellent features as a high speed recording wire material except abrasion resistance and the tip portion of the wire 1 is applied with a titanium nitride film 3 having high hardness in order to compensate abrasion resistance, the wire 1 is provided with excellent features as a whole and the durability of wire 1 or a recording head is improved resulting in realization of high speed recording. |
