ABSTRACT:
In a recording/reproducing device for use in recording and reproducing data on and from a recording medium while moving read/write head means relative to the recording medium in a moving direction, which comprises a carriage supporting the read/write head means and guided by a guiding member in the moving direction, and a voice coil motor comprising a voice coil and a magnetic circuit device for driving the carriage in the moving direction. The carriage has a coil holding portion by which the voice coil is fixedly held in the condition that the coil axis is arranged in the moving direction. The voice coil is applied with a driving electric current for driving the carriage. The magnetic circuit device is fixedly disposed adjacent to the voice coil to generate a magnetic field intersecting the driving current flowing through the voice coil, the voice coil moving in the moving direction together with the carriage by an interaction of the driving current and the magnetic field.
