摘要： A motor includes a turntable and a rotor holder unified with each other by insert-molding. The turntable includes a protrusion portion protruding radially outward beyond a cylinder portion and a substantially cylindrical covering portion extending downward from an radial inner end of the protrusion portion to cover an outer circumferential surface of the cylinder portion. The rotor holder has a radial outer end portion arranged in the same radial position as an outer circumferential surface of the covering portion or arranged radially inward of the outer circumferential surface of the covering portion. For this reason, a sliding contact area between a mold and the rotor holder is reduced. This helps suppress sliding contact between the mold and the rotor holder during a mold releasing process, consequently suppressing degradation of the mold.
摘要翻译：电动机包括通过嵌入成型彼此统一的转台和转子架。转盘包括从圆筒部分径向向外突出的突出部分和从突起部分的径向内端向下延伸以覆盖圆筒部分的外圆周表面的大致圆柱形的覆盖部分。转子保持器具有径向外端部，其布置在与覆盖部分的外周表面相同的径向位置或者布置在覆盖部分的外周表面的径向内侧。因此，模具和转子保持架之间的滑动接触面积减小。这有助于在脱模过程中抑制模具和转子保持器之间的滑动接触，从而抑制模具的退化。

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.
