    摘要： A chucking device for removably holding a disk with a central opening, includes a shaft coaxially arranged with a specified center axis; a turntable fixed to the shaft, the turntable having a disk support surface for supporting the disk; and a resin-made cone arranged axially above the turntable, the cone including a shaft-fixed portion fixed to the shaft, a disk holding portion having an annular disk holding surface inclined radially outwardly and axially downwardly, and an arm portion for radially interconnecting the shaft-fixed portion and the disk holding portion. Herein, the arm portion includes a support portion extending radially outwardly from the shaft-fixed portion and an elastically deformable portion joined to the support portion for being elastically deformed to axially downwardly move the disk holding portion as the disk comes into contact with the disk holding portion.

    摘要： A space for accommodating therein a portion of an optical pickup mechanism is arranged below a disk loading portion of a turn table member of a chucking mechanism of the present invention. The space is arranged axially below a disk mounting surface. Since such space is provided, a recording/reproducing portion will be allowed to move closer to a brushless motor, and therefore a second lens arranged further away from the brushless motor will be allowed to move radially inward of a recording/reproducing area of an optical disk.

    摘要： A turntable for a storage disk drive apparatus includes a plate member made of a ferromagnetic material and a central resin member arranged at the center of the plate member and provided with an outer peripheral portion positioned above the plate member. The central resin member includes claws extending downwards from the outer peripheral portion and claw position holes overlapping with the claws in the direction parallel to the center axis of the central resin member. The claw position holes include inner surfaces spaced apart from an edge of the plate member. The inner surfaces are defined by the resin. The central resin member includes a resin layer extending in the direction perpendicular to the center axis. The resin layer exists between the portion of the edge of the plate member around the claw position holes and the claw position holes.
