摘要： Embodiments of the present invention relate to systems, methods, and computer readable media for calibrating storage devices such as hard drives. Storage devices include storage media that are divided into differing data zones having differing data densities. A testing system initiates a series of microjog tests in the storage that are configured to determine read/write offsets indicating a distance between a write position associated with a particular location and a preferred read position for the location. To calibrate the storage device, the testing system or other product measures read/write offsets at different locations on an actuator stroke within a read/write zone. The storage device then determines predicted read/write offsets for the zone based upon the determined read/write offsets at locations in the read/write zone.

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.
摘要翻译：根据实施例的系统和方法可以用于将数据重写到可旋转的存储介质。当在数据写入操作期间写入元件的位置不在阈值内时，可以保持在元素的位置不在阈值内时写入的数据的指示。当包括可旋转存储介质的设备没有其他数据传输操作时，可以重写写入元素不在阈值内的数据。以这种方式，可以重新写入由于在数据写入操作期间写入元件的错位可能被认为不太可靠的数据，使得数据可以被放置得更靠近数据轨道中心线。

摘要： An electronic storage device provides rapid data availability. The rapid data availability relates to sequences of reads and writes performed by the ESD responsive to critical events, such as power-up sequences or sequences of read and/or write operations. A sequence of reads is performed upon detecting a critical event. A record of reads to be performed is maintained in a reserved area of the disk. In the case of similar but different events, such as host power-up from an off state and host power-up from a hibernation state, different read and write sequences are performed for each scenario. Improvements to the sequence of reads and/or writes may be determined, thereby enabling the ESD to improve its response to critical events over time.
摘要翻译：电子存储设备提供快速的数据可用性。快速数据可用性涉及由ESD响应于关键事件（例如上电序列或读取和/或写入操作的序列）执行的读取和写入序列。在检测到关键事件时执行读取序列。要执行的读取记录保留在磁盘的保留区域中。在类似但不同的事件（例如从关闭状态的主机上电以及从休眠状态的主机上电）的情况下，针对每个场景执行不同的读取和写入序列。可以确定对读取和/或写入序列的改进，从而使ESD能够随着时间改进其对关键事件的响应。

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： A two-step self-servowriting process first writes an intermediate pattern based on a reference pattern, and then writes a final pattern based on the intermediate pattern, wherein the reference pattern can be a printed media or a spiral pattern. Such an approach can be utilized to reduce the noise/runout, eliminate timing eccentricity, and increase the sample rate of the final pattern. 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： The amount of position error written into a servo burst pattern can be reduced by using additional media revolutions to write the pattern. Where the edges of two servo bursts are used to define a position on the media, trimming the first burst and writing the second burst on separate revolutions of the media will result in a different amount of position error being written into each burst. The end result will be a reduction in the overall error in position information. In order to further reduce the position error given by a burst pair, each burst also can be trimmed and/or written in multiple passes. Additional bursts can also be written, such as for each data track centerline. The overall error in position should decrease as the number of passes used to write a burst pair increases. Also, additional bursts can be written in separate passes in order to further reduce position error while avoiding coherence concerns. 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.
摘要翻译：通过使用额外的介质转数来写入图案，可以减少写入伺服突发图案的位置误差量。在两个伺服脉冲串的边缘用于定义介质上的位置的情况下，修剪第一个脉冲串并将第二个脉冲串写入介质的分开的转数将导致不同量的位置误差被写入每个脉冲串。最终结果将是减少位置信息的总体错误。为了进一步减少由突发对给出的位置误差，每个突发也可以被多次修剪和/或写入。也可以写入附加的脉冲串，例如对于每个数据轨道中心线。随着用于写入突发对的通过次数增加，位置的总体误差将减小。而且，为了进一步减少位置误差同时避免一致性问题，可以单独传递附加的脉冲串。本说明书不是对本发明的完整描述或限制本发明的范围。本发明的其它特征，方面和目的可以通过对说明书，附图和权利要求的评述来获得。

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.
