摘要： A structure has a focus coil wound or affixed on sides of a lens holder holding an objective lens and two or more permanent magnets spaced from each other and facing the focus coil with their magnetic poles directed in the same direction with respect to one side of the focus coil, wherein the density distribution of the magnetic flux passing through the side of the focus coil facing the permanent magnets has two or more maximum points. This allows for a large assembly error, or tolerance, and reduces inclination of the optical axis in an objective lens actuator used in the optical pickup of various kinds of optical disk devices.

摘要： An objective lens actuator is provided which is equipped with an actuating mechanism for actuating an objective lens mounted on a lens holder of an apparatus adapted to write or read information into or from a recording medium. The actuator moves the lens and its holder in two directions, one direction being substantially parallel to a surface of the recording medium such that the objective lens makes turning motion about a pivot axis oriented substantially normal to the surface of the recording medium and the other direction being vertical, with the lens and holder sliding vertically relative to the pivot axis. The actuator is equipped with at least one parallel driving coil for driving the movable section in the parallel direction and with at least one parallel driving magnetic circuit for imparting a magnetic flux to the parallel driving magnetic circuit. The actuator is arranged such that both drive forces, which are generated as a result of respective actions of electric currents flowing through at least two faces of the parallel driving coil and magnetic fluxes of the parallel driving magnetic circuit, constitute turning forces for turning the objective lens about an axis in the same rotational direction, thereby enhancing driving precision.

摘要： A disk drive according to the present invention includes: a cartridge holder; two guide walls arranged near the holder opening of the cartridge holder; a pair of opening/closing levers that have engaging portions to engage with portions of the cartridge and that turn; lever biasing springs for biasing the opening/closing levers; and an interlocking mechanism that makes the opening/closing levers rotate in synchronization with a clamp holder. The opening/closing levers turn such that when the cartridge starts to be inserted or finishes being ejected, the engaging portions get engaged with the cartridge with a narrower gap left between them than the gap between the guide walls and that when the cartridge gets loaded, the gap between the engaging portions becomes wider than the gap between the guide walls.
