ABSTRACT:
A flexible disk unit having a reduced thickness includes a spindle motor for rotating a magnetic recording medium having a magnet at its outer periphery, a movable carriage supporting a magnetic head and a stator surrounding the spindle motor and including a coil opposed to the magnet. The stator has a recess which is adapted to surround the tip of the movable carriage when the carriage is moved towards the magnetic recording medium. A head shield portion is disposed between the stator and the magnetic for shielding leakage flux in the direction of the magnetic head.
