description PURPOSE: A magnetic head and a producing method thereof are provided to improve life span of the magnetic head through coating a diamond like carbon film having excellent abrasion resistance and chemical stability. CONSTITUTION: A magnetic head is coated by a diamond like carbon film(6c) having a thickness of 0.5 micrometer. Herein, an error rate in reading a magnetic recording medium is less than 0.5%. Moreover, a head is formed by a material selected from a group formed by metal, ceramic, and polymer. Herein, the diamond like carbon film is combined on a surface of the head in a plasma chemical deposition method. Herein, an adhering force is improved by using an argon sputtering method by using high voltage bias, and by forming an adhering force improving layer inclining density of metal by forming a metal layer and a metal composition layer between the diamond like carbon film and the magnetic head surface.
