Magnetic printing head having a high signal-to-noise ratio |
摘要 |
The signal-to-noise ratio as measured by the ratio of the full select magnetic field levels to the half select magnetic field levels, is improved in a coincident current magnetic printing head by providing means for producing a bias magnetic field which is at least somewhat opposed to the signal magnetic fields.
