摘要： A light beam emitted from a light source is focused by an objective lens onto an information recording surface of an optical information recording medium. The objective lens has a substantially truncated-cone-shaped portion on its surface on the side of the optical information recording medium. This makes it possible to prevent interference with a DVD-RAM cartridge and ensure optical compatibility with a BD and a DVD.

摘要： In an objective lens driving device having a movable portion including an objective lens held by a lens holder, a damage prevention system for preventing the objective lens or a disk from being damaged when the objective lens or the lens holder collides with the disk is provided. The damage prevention system is constituted by inserting a protecting member formed of an elastic member in a fitting portion on an upper surface of the lens holder while being deformed. In this manner, it is possible to generate a sufficient holding power with respect to the protecting member without using glue or the like.

摘要： Guide parts and driving parts are independently provided for an optical head and a magnetic bias field generator, and a relative position control part controls the relative positions of the two so that the both can access recording medium tracks individually. Furthermore, a magnetic pattern track for use as the detection signal of the absolute position of the magnetic bias field generator to the magneto-optical recording medium is formed on the magneto-optical recording medium itself, and a positioning control part of the magnetic bias field generator using this magnetic pattern track is provided, so that the positioning control of the absolute position of the magnetic bias field generator with respect to the magneto-optical recording medium may be realized.
