用光ヘツド。[Claims for Utility Model Registration] An optical system such as a laser, an anamorphic biprism, and an objective lens is attached, and a rectangular coil with flattened coils fixed to both end faces is attached, and the anamorphic biprism is attached to the anamorphic biprism on the substantially center side. A substantially rectangular driven body with a sliding member attached near the bent optical path between the anamorphic prisms constituting the biprism, an inner yoke loosely inserted into the rectangular coil, and a magnet facing the flat coil. The driving body includes fixed outer yokes that are erected on both ends in close proximity to each other, and a sliding member on which the sliding member slides when the driven member is displaced, is provided approximately at the center side. An optical head for an optical recording/reproducing device, characterized in that:
