ABSTRACT:
In a magnetic recording/reproducing device, a voice coil motor includes a voice coil and a magnetic circuit for producing a magnetic field intersecting the electric current flowing through the voice coil. The voice coil motor drives a carriage holding a magnetic head. A flexible printed circuit is disposed adjacent to the voice coil for feeding the electric current to the voice coil and sending signals to and from the magnetic head. Between the voice coil and the flexible printed circuit is interposed a magnetic shield for preventing to noise from influencing the flexible printed circuit upon feeding the electric current to the voice coil.
