<p><P>PROBLEM TO BE SOLVED: To provide a magnetic head device having a shielding effect by preventing influence of external noise. <P>SOLUTION: The magnetic head device 10 includes a circuit board 11, a magnetic head 20, and a control IC 40. The magnetic head 20 is mounted on one surface of the circuit board 11, while the control IC 40 is mounted on the other surface. A solid pattern 12 is formed on the surface of the circuit board 11 on which the magnetic head 20 is mounted. The solid pattern 12 is used as a ground potential. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
