ABSTRACT:
A magnet/block assembly is provided for creating and distributing a magnetic field that interacts with a magnetic field produced by an actuator coil in a disc drive system. The magnet/block includes permanent magnets and a block comprised of a back iron separated from a front iron by a gap space. A loop is integrally formed with the back iron and the front iron at an end of the gap space to provide a path for flux to be conducted between the front iron and the back iron.
