Recording head for magneto-optical recording device and magneto-optical recording device comprising the same

摘要

A recording head for magneto-optical recording in a first-surface recording configuration comprises a transparent aperture ( 8;22;32 ), in a plane intended to be substantially parallel to a recordable medium ( 2 ), in use. The head is arranged to provide an optical path allowing a bundle of light ( 6 ) to pass through the transparent aperture ( 8;22;32 ) onto the recordable medium ( 2 ), and further comprises a central magnetic head structure ( 11;20;34 ) comprising a flux guide ( 12;24;35 ), positioned so as to partially obstruct the transparent aperture ( 8;22;32 ). The central magnetic head structure ( 11;20;34 ) is of a substantially larger dimension in a first direction (x) parallel to the plane than in a second direction (y) parallel to the plane.
