    摘要: An apparatus and method for correcting static and dynamic imbalance with a single mass in a hard disk drive is disclosed. The method provides for determining a static imbalance of a hard disk assembly and for determining a dynamic imbalance of the hard disk assembly. A greater imbalance from the static imbalance and the dynamic imbalance is determined. A single mass is applied to the hard disk assembly to correct the greater imbalance.

    摘要: A completely circumferential shroud is provided around the motor hub flange of a hard disk drive spindle motor. The shroud is continuous, smooth, and uniform, and formed at the same axial height as the flange to reduce air flow disturbances that are generated by the rotating motor hub flange. Unlike prior art designs that provide openings to accommodate the actuator, the present design has no openings or irregular shapes that can cause air flow disturbance. Air flow disturbance, especially when near the actuator arms or head suspensions, can impact track misregistration. In addition, the probability of circulating contamination particles inside the motor out into the disk drive enclosure is also reduced due to less irregular airflow patterns.

    摘要: A method for centering and securing data storage disks to the hub of a spindle motor in a hard disk drive has a chamfer and a countersink on the top of the spindle motor shaft center. During the hard disk drive assembly process, a disk centering tool engages and uses these features to locate and center the disks that are installed on the spindle motor. The features are closely toleranced to provide a very precise centering feature for mounting and aligning the media disks with respect to the hub and the spindle motor. The present design reduces the complexity of the tooling and fixtures required to complete the assembly. As a result, the overall part cost is reduced and the manufacturing yield is improved.

    摘要: A spindle motor is equipped with pre-installed adjustable balance clips on a stainless steel motor hub to facilitate better balance correction. A balance clip holder feature is formed in the hub and has grooves to hold the balance clips. The balance clip holder can be an integrally formed part of the hub, or it can be a separate piece that is assembled to the hub before the complete motor is assembled. In addition, the balance clips are provided with an improved coating to reduce friction during adjustment of the clips in the balance process. Each clip has a coating of nickel-Teflon to achieve a better coating quality and cleanliness over prior art designs. The nickel-Teflon combination yields unexpected results, such as a significantly smoother surface with more uniform coating thickness, and significantly less particle sloughing to reduce contamination.
