Abstract
A translational, bias-field device for a magneto-optical system having a magneto-optical recording element moving through a first 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. Two bars are positioned in a spaced apart relationship, disposed substantially parallel to each other and supported by the housing. A permanent magnet is positioned adjacent the recording element for providing the first magnetic field to the recording element, and is attached to the bars which induce translational movement to the magnet when the magnet is induced with a second magnetic field. A coil is positioned adjacent to the magnet which, when energized, imparts the second magnetic field to the permanent magnet.
