摘要： A rotatable media storage device operates using multiple disk spin-speeds, e.g., a reduced spin-speed and a nominal spin-speed. A disk is spun up to a reduced spin-speed and an initial data transfer is began while the disk spins at the reduced spin-speed, if an amount of work that has been requested is below a threshold. The disk is spun up to a further spin-speed (e.g., a nominal spin-speed), which is greater than the reduced spin-speed, and the initial data transfer is began while the disk spins at the further spin-speed, if the amount of work that has been requested is above the threshold. Alternative embodiments using multiple disk spin-speeds are also provided.

摘要： Embodiments of the present invention determine the offset of a first burst of a burst pair from a centerline. This can be used to determine the desired offset position for a second burst of the burst pair. The target signal to provided the data storage unit for writing the second burst can take into account the transfer function of the controller and the physical plant so as to more accurately write at the desired offset position.

摘要： The misplacement of a servo burst during a servowriting or self-servowriting process can be corrected by erasing and re-writing that burst. In addition, WORF information of a track can be saved in memory for future servowriting and/or can be utilized to compare with a pre-determined threshold to identify servo bursts to be repaired. Alternatively, a batch writing approach can be used to minimize the time needed to re-write misplaced bursts. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

摘要： Systems and methods in accordance with embodiments can be used to re-write data to a rotatable storage medium. When a position of a write element is not within a threshold during a data write operation, an indication of data written while the position of the element was not within the threshold can be maintained. When the device including the rotatable storage medium is free from other data transfer operations, the data written while the element was not within the threshold can be re-written. In this manner, data that may be considered less reliable due to the misplacement of a write element during a data write operation can be re-written such that the data can be placed closer to a data track centerline.

摘要： Attributes of a hard disk drive are stepped between different power consumption levels to optimize the trade-off between minimizing power consumption and maximizing performance depending on whether AC or battery power is used. One attribute is the clock speed which can be changed for a number of disk drive components including the processor, the external interface bus and the memory interface bus. The system power supply voltage can further be changed in a number of components integrated together on an application specific integrated circuit (ASIC). Further, spindle motor rotation speed can be changed, or the spindle motor spun-down. Further, actuator movement by the VCM can be controlled to provide faster movement during track seek operations when high performance is desired. Additionally, write-back caching parameters are adjusted based on the source of power for the hard drive, be it battery, AC power, or a combination.

摘要： Systems and methods in accordance with embodiments can be used to re-write user data to a rotatable storage medium. When a position of a write element is not within a threshold during a data write operation, a part of a data track potentially affected by the write operation, while the position of the write element was not within the threshold, can be determined. When the device including the rotatable storage medium is free from other data transfer operations, the data of the data track potentially affected by the write operation can be re-written. In this manner, data that may be considered less reliable due to the misplacement of a write element during a data write operation, can be re-written.

摘要： To account for head misplacement while servowriting, adjustments to thresholds used during writing and/or trimming of servo information can be used. A threshold can be used to disable servowriting when it is determined that servo information will not be written and/or trimmed at a desired location or within a threshold distance of a desired location. In multiple pass servowriting, a threshold can be adjusted for a pass or step or portion thereof using a position-error during a corresponding operation. For example, the position-error while trimming a first servo burst can be determined. Using the position-error, the threshold can be adjusted. The adjusted threshold can be used while writing a corresponding second servo burst. The threshold can be increased in a direction opposite to the determined position-error and decreased in the direction of the determined position-error. In this manner, the probability that the two bursts will identify a desired location can be increased.
摘要翻译：为了在伺服驱动时考虑磁头错位，可以使用在伺服信息的写入和/或修整期间使用的阈值的调整。当确定伺服信息不会在期望的位置或期望位置的阈值距离内被写入和/或修剪时，可以使用阈值来禁用伺服驱动。在多通道伺服驱动中，可以在相应的操作期间使用位置误差来调整通过或步进或其部分的阈值。例如，可以确定修整第一伺服脉冲串时的位置误差。使用位置误差，可以调整阈值。可以在写入对应的第二伺服脉冲串时使用调整后的阈值。阈值可以在与所确定的位置误差相反的方向上增加，并且在所确定的位置误差的方向上减小。以这种方式，可以增加两个突发将识别期望位置的概率。

摘要： The misplacement of a servo burst during a servowriting or self-servowriting process can be corrected by erasing and re-writing that burst. A servo pattern can be selected that has sufficient radial separation between bursts such that if a burst is re-written and trimmed there should be no damage to adjacent bursts. The radial separation can be selected to be greater than the width of the appropriate write element in order to allow for some misplacement of the element during the erasing and/or re-writing of the misplaced burst. Alternatively, a batch writing approach can be used to minimize the time needed to re-write misplaced bursts. In addition, WORF information of a track can be saved in memory for future servowriting and/or can be utilized to calculate a threshold for identifying servo bursts to be repaired. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
