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 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. 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： To account for head misplacement while servowriting, conditional writing and/or trimming of servo information can be used. Conditional servowriting allows servowriting to be disabled 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. For example, if a distance between a write element or a predicted location of servo information and a desired location of the servo information or write element exceeds a threshold, writing and/or trimming can be inhibited. Servowriting can be resumed when it is determined that servo information will be written or trimmed at a desired location or within a threshold distance of a desired location. A servowriting step or pass is not re-started when the threshold is exceeded and those wedges for which servo information was not written and/or trimmed can be attempted during subsequent revolutions of the rotatable storage medium. Various methods can also be used to account for servo information that is not written and/or trimmed after a number of revolutions, including increasing threshold(s), writing and/or trimming unconditionally, and re-computing WORF values for a reference disk. Additionally, other techniques including write current variation and individual passes for writing and trimming can be used with various embodiments using conditional writing techniques.

摘要： Methods for searching for a servo address mark (SAM) pattern using multiple sets of servo demodulation detection parameters are provided. A SAM pattern is searched for using a first set of servo demodulation detection parameters. The SAM pattern is also searched for using a second set of servo demodulation parameters, wherein at least one servo demodulation parameter in the second set is different than a corresponding parameter in the first set. Example servo demodulation parameters include staring servo automatic gain control (AGC) values and starting servo phase lock loop (PLL) values.

摘要： A disk drive includes a disk having a first servo burst written with advancing phase as a radial distance on the disk increases, and a second servo burst written with decreasing phase as a radial distance on the disk increases, and a transducing head, and a read channel. The disk drive also includes an element for shifting the phase of the signal produced by the first burst pattern with respect to the signal produced by the second burst pattern by an amount sufficient to substantially cancel distortion in a signal produced by the first servo burst with distortion in a signal produced by the second servo burst when the signal from the first servo burst is added to the signal from the second servo burst.

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： 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： In order to account for the misplacement of a write element during a servowriting process, the width of the information being written can be varied. In a self-servowriting disk drive, for example, the write current supplied to a read/write head can be adjusted to vary the width of information, such as servo bursts, written by the head. By calibrating the head and determining the misplacement of the head while writing, an edge of a servo burst can be placed in the desired position regardless of the misplacement of the head simply by adjusting the width of the written burst. 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.
