PROBLEM TO BE SOLVED: To provide a magnetic head driving device in which the characteristic impedance of a conductor line path is reduced. SOLUTION: A write interconnect pattern W1 are configured with line paths LA1-LA3. An end portion of the line path LA1 is connected to an electrode pad 13a, and an end portion of each of the line paths LA2 and LA3 is integrated with the other end portion of the line path LA1. The other end portions of the line paths LA2 and LA3 are connected to an electrode pad 14b or 14d, respectively. A write interconnect pattern W2 includes line paths LB1-LB4. An end portion of the line path LB1 is connected to an electrode pad 13b, and an end portion of each of the line paths LB2 and LB3 is integrated with the other end portion of the line path LB1. The other end portion of the line path LB3 and an end portion of the line path LB4 are electrically connected at an intersection region CN1. The other end portions of the line paths LB2 and LB4 are connected to electrode pads 14a and 14c, respectively. COPYRIGHT: (C)2010,JPO&INPIT
