摘要： In a low-profile disk drive device, the hard-disk carrying face of the spindle motor hub is finished to leave a spiral-patterned cutting track. Leaving the spiral-patterned cutting track increases the roughness of the carrying face, but seen in terms of the cutting-track hill portions themselves the surface unevenness is reduced. Because the disk is supported on the hill portions, warpage in the disk is attenuated.

摘要： A motor includes a shaft component, an upper plate portion, a lower plate portion, and a sleeve portion. The shaft component includes an inner shaft portion and an outer shaft portion. The upper plate portion defines a single monolithic member with one of the inner shaft portion and the outer shaft portion. The lower plate portion defines a single monolithic member with the other of the inner shaft portion and the outer shaft portion. The sleeve portion is disposed between the upper plate portion and the lower plate portion. A radial gap is defined between the sleeve portion and the outer shaft portion. A fixing range in which the outer shaft portion and the inner shaft portion radially overlap is arranged. At least a portion in an axial direction of the fixing range radially overlaps with an existing range in the axial direction of the radial gap.

摘要： Using a simple and inexpensive method, a reliable spindle motor having a simple and inexpensive structure is afforded, in which contact failure of the FPC does not occur even when the motor undergoes external impact. An extending portion is provided radially outer side of an annular recess of a base. The extending portion has a step whose radially outer side is higher, and a through hole formed such as to pass through the base from its inside to outside. A FPC is disposed on an upper surface of a stator. The FPC is fixed to a lower surface of the base through the through hole. The bending height and the bending angle of the FPC are minimized by providing the step having appropriate height so that the FPC is not easily peeled off even when subject to external impact.

摘要翻译： 使用简单且廉价的方法，提供了具有简单且便宜的结构的可靠的主轴电机，其中即使当电动机经受外部冲击时也不会发生FPC的接触故障。 在基部的环形凹部的径向外侧设置有延伸部。 延伸部分具有径向外侧较高的台阶，以及形成为从内向外穿过底座的通孔。 FPC定位在上表面上。 FPC通过通孔固定在基座的下表面。 通过提供具有适当高度的台阶使FPC的弯曲高度和弯曲角度最小化，使得FPC即使经受外部冲击也不容易剥离。

摘要： A motor includes a shaft component including an inner shaft portion and an outer shaft portion. A radial gap is defined between a sleeve portion and the outer shaft portion. A radial dynamic pressure generating groove array is arranged on at least one surface of an inner circumferential surface of the sleeve portion and an outer circumferential surface of the outer shaft portion, which define the radial gap. The radial dynamic pressure generating groove array includes an upper and lower radial dynamic pressure generating groove array. The inner shaft portion is fixed to the outer shaft portion in an interference fit. An axial range of a fixing region of the inner shaft portion and the outer shaft portion which is in the interference fit is included in a range between the upper and lower radial dynamic pressure generating groove array.

摘要： In a motor of a motor unit, a base plate includes a raised portion protruding from a surrounding portion on a side of the stator portion opposite to a rotor portion. A raised face of the raised portion is perpendicular to a central axis and is formed in an annular shape around the central axis. The raised face of the raised portion protrudes lower than a lower surface of a sticker member stuck around the raised portion to thereby close a hole portion formed around the raised portion.
