摘要： One aspect of the invention relates to an apparatus and method for retaining a disc drive head disk assembly (HDA) during a servo track writing procedure. The HDA includes a base, a disc stack coupled to a spindle rotatably attached to the base by a spindle shaft, and an actuator assembly pivotally attached to the base at a pivot shaft. Attached to one end of the actuator assembly proximal the disc stack is one or more transducers for reading/writing information from/to the discs. In one embodiment, the method includes restraining the ends of the spindle shaft and pivot shaft during servo track writing so that relative deflection therebetween is minimized. That is, all but rotational motion of the components is substantially eliminated. An apparatus for restraining the ends of the spindle shaft and pivot shaft is also provided. By so restraining the shaft and spindle, the servo information written by the transducers is concentric to the rotation of the disk, reducing track misregistration and improving maximum track density.
摘要翻译：本发明的一个方面涉及一种用于在伺服轨迹写入过程期间保持盘驱动头盘组件（HDA）的装置和方法。 HDA包括底座，联接到通过主轴可旋转地附接到基座的心轴的盘组，以及在枢轴处枢转地附接到基座的致动器组件。靠近盘片组件的致动器组件的一端附接有用于从/向盘读/写信息的一个或多个换能器。在一个实施例中，该方法包括在伺服轨迹写入期间限制主轴和枢转轴的端部，使得它们之间的相对偏转最小化。也就是说，基本上消除了部件的旋转运动。还提供了用于限制主轴和枢轴的端部的装置。通过这样限制轴和主轴，由换能器写入的伺服信息与盘的旋转同心，减少轨道重合失调并提高最大轨道密度。

摘要： A servo track writer assembly and method are provided for recording servo pattern information on a disc. The servo track writer assembly includes a spindle assembly, an actuator assembly and a servo recording head. The spindle assembly has a hub, which supports the disc and a spindle motor for rotating the hub. The actuator assembly has an actuator arm supported by an actuator bearing for positioning the actuator arm relative to the disc. At least one of the spindle motor and the actuator bearing has a gas-lubricated bearing with a working fluid, which includes helium. The servo recording head is supported by the actuator arm relative to the disc to record the servo pattern information on the disc as the spindle motor rotates the disc and the actuator bearing positions the actuator arm.

摘要： One aspect of the invention relates to an apparatus and method for loading and securing a disc drive head disk assembly (HDA) in a servo track writing apparatus. The HDA includes a base, a disc stack coupled to a spindle rotatably attached to the base by a spindle shaft, and an actuator assembly pivotally attached to the base at a pivot shaft. Attached to one end of the actuator assembly proximal the disc stack is at least one transducer for reading/writing information from/to the discs. In one embodiment, the apparatus comprises a vacuum block having an air bearing and a vacuum stiffener. The vacuum stiffener is selectively used simultaneously with the air bearing to preload the latter. Alternatively, the vacuum stiffener is used independently of the air bearing to vacuum couple the vacuum block to a guide surface. By allowing both vacuum preload and vacuum coupling, the vacuum block of the present invention provides precise HDA placement and retainment with little or no manual operator intervention. Further it reduces the complexity of the STW by eliminating the need to provide a separate preload device.

摘要： An actuator assembly including one or more actuator arms, wherein each of the actuator arms defines a clasp hole and a clamp-opening hole and a slot running between the clasp hole and clamp-opening hole, and optionally, a second slot running from the clasp hole to a distal end of the actuator arm, thereby creating two clasp fingers. A flex suspension assembly is included with a protrusion, such as a boss and a head on a distal end. The flex suspension assembly is coupled to the actuator arm by resiliently increasing the diameter of the clasp hole so as to allow the boss on the flex suspension assembly to be inserted into the clasp hole. With the boss is inserted, the clasp hole is allowed to revert to its original diameter, thereby clamping the boss in the clasp hole. A method for assembly is also provided.

摘要： A servo writer support assembly supports a disc drive storage device relative to an orthogonal coordinate system comprising X, Y and Z axes during servo writing. The support assembly includes a support body, a yaw registration feature, a pitch registration feature and a locating post. The yaw registration feature is engageable with the disc drive storage device for limiting rotation of the disc drive storage device about the Z axis. The pitch registration feature is engageable with the disc drive storage device for limiting rotation of the disc drive storage device about the X and Y axes. The locating post extends from the support body parallel to the Z axis and includes a registration surface having a tangent that is oblique to the Z axis. The registration surface is engageable with the disc drive storage device for limiting translational movement of the disc drive storage device along the X, Y and Z axes.
