Abstract: 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.

Abstract: The amount of position error written into a servo burst pattern can be reduced by using additional media revolutions to write the pattern. Where servo bursts are used to define a position on the media, trimming a first burst and writing a 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 combination of bursts, each burst also can be trimmed and/or written in multiple passes. The overall error in position should decrease as the number of passes used to write a burst combination increases. 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.

Abstract: 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.

Abstract: 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.

Abstract: Methods in accordance with the present invention can include determining a position of a head along a stroke by locating one or more marker-zones printed to a reference surface of a disk. The one or more marker-zones can be printed to a portion of the reference surface as one or more pulses from a template pattern that can further comprise a plurality of chevrons. In one embodiment, each pulse can trace the motion of the stroke along at least a portion of the radius of the reference surface. A pulse can identify a marker-zone edge when the pulse disappears at some radius from the center of the disk. By moving the head along the stroke, the marker-zone edge can be detected and a gross position determined. A fractional position can be determined by measuring a phase of a chevron located at substantially the same radial location as the edge.

Abstract: Template patterns in accordance with the present invention can be applied to improve printed media self-servo writing by reducing PES noise and SAM error-rate at an outer diameter of a reference surface of a disk. In one such template pattern, zig-bursts within a servo wedge describing radial positioning are replaced with pulses at an inner diameter of the reference surface such that head skew at the inner diameter is a limiting factor for pattern frequency at the inner diameter. This description is not intended to be a complete description of, or limit the scope of, the invention.

Abstract: A method for retrieving critical data determined to be requested by a host device in the near future and stores it in cache. A hard drive retrieves and provides the critical data to the requesting host upon receiving the request, thereby eliminating the time required to respond to the request due to media accessing. The critical data may be related to power-on of the computer, such as boot sector FAT system data. Thus, the cache of the present invention may use old data rather than new data or the last data accessed.

Abstract: A method for retrieving critical data determined to be requested by a host device in the near future and re-allocating the critical data on the hard drive medium. The hard drive provides the critical data to the requesting host upon receiving the request, thereby eliminating the time required to respond to the request due to media accessing. Thus, the cache of the present invention may use old data rather than new data or the last data accessed. The critical data can be written to reserved areas of the media that provide desirable read characteristics. In this aspect, the present invention may trade drive capacity and/or media write speed for media read speed. The critical data maybe re-allocated and placed in sequential order, thereby saving time from seeking to different locations over the media. Critical data may stored in FLASH memory, providing quicker data access while consuming less power. While the hard drive is in low power states, other data can be written to FLASH in order to conserve energy.
