ABSTRACT:
A translational, bias-field device for a magneto-optical system having a magneto-optical recording clement moving through a magnetic field created by the bias-field device so that information can be selectively recorded on or erased from the recording element, the device comprises a housing and a first rail for enabling translational movement attached to the housing. A permanent magnet is positioned adjacent the recording element for providing the magnetic field to the recording element, and is attached to the first rail which enables translational movement of the magnet. A mechanical driver is attached to the magnet which driver imparts movement the permanent magnet.
