PURPOSE:To reduce a waste caused by a failure of each part, and also to execute an adjustment with a high accuracy by providing plural supporting parts on a carriage constituted as a separate body, so that the position can be adjusted. CONSTITUTION:''1'' and ''0'' face head arms 1, 7, and a carriage 6 are constituted as a separate body, respectively, and the arms 1, 7 are provided so that the position can be adjusted. Also, a body 17 of the arm 7 is formed from a metal and also formed so that a heat conduction is small, by which the following advantage is obtained. A size variation due to a temperature of the arm becomes small, and an error of a track position of a ''0'' face head, and a shift of a relative position of a track of ''0'' and ''1'' face heads become small. In case of a failure of the ''0'' face head arm, and in case of a failure of the carriage, it will do that only the arm and only the carriage are replaced, respectively. In this way, a slide torque to a guide bar of the carriage is adjusted easily, and a failure of the slide torque can be reduced. |
