Abstract
A magneto-optic transducer for providing an optical indication of variations in magnetization in a magnetic storage medium located along a predetermined path. The transducer has a thin film of magneto-optic material with an edge positionable closely adjacent the storage medium path so that the magneto-optic film is magnetized in accordance with the magnetization in the storage medium. The magneto-optic film is supported such that polarized light projected along an incident optical path, convergent with the storage medium path at an acute angle, intercepts the magneto-optic film substantially normally and is reflected back generally along the incident optical path.
