摘要： Track pitch for writing tracks on a disk is determined based on an available stroke across the disk. The available stroke is identified by searching across the disk for where information can be written and read. The track pitch is determined for writing tracks on the disk based on the available stroke across the disk. Tracks are written on the disk based on the determined track pitch.

摘要： A method and apparatus for determining embedded runout correction values when self-servo writing or partial self-servo writing is disclosed. In one embodiment, a disk surface, which has servo information written thereon, is provided. The servo information is grouped into 1x servo sectors and 2x servo sectors, and the 1x servo sectors and the 2x servo sectors form a plurality of tracks. A read head servos on the 1x servo sectors associated with a track. Both position error signals due to repeatable runout for the 1x servo sectors and information related to position error signals due to repeatable runout for the 2x servo sectors are determined, while servoing on the 1x servo sectors. Embedded runout correction values for the 1x servo sectors and the 2x servo sectors are calculated.

摘要： A method and apparatus for applying adaptive non-linear repeatable runout compensation in a disk drive is provided. In one embodiment, the present invention provides a disk surface having a track written thereon, wherein the track includes repeatable runout. A non-linear converge gain is applied to compensate for the repeatable runout. In one embodiment, the converge gain is based upon an amplitude of a position error signal associated with the repeatable runout at a frequency of rotation of the disk surface (or multiple thereof).

摘要： A disk drive measures the radial misposition of tracks and repositions the tracks at regularly spaced intervals. Written in runout (WRO) in servo bursts is determined to calculate track spacing and squeeze among adjacent tracks. Tracks with improper spacing are repositioned by adding a squeeze correction term to the servo wedges. Thereafter, when the disk drive operates to store data, the servo bursts are used to calculate a position error signal (PES), and the squeeze correction term is combined with the PES to position the head at a proper track radius.

摘要： A cellular telephone is configured to perform procedures to protect against malfunction or damage to an HDD or other mass storage device in the cell phone, in response to receiving an indication of an incoming call. The protection procedures can include delaying one or more cell phone operations, and/or sending instructions to an HDD or other mass storage device including instructions to complete an operation, suspend an operation, park a head and/or spin down an HDD. In a cell phone which provides for extended playback, e.g., of audio or video, the cellular telephone preferably is configured to avoid interruptions of playback, e.g., during suspension or HDD operation.

摘要： Methods and structures for appending metadata with recorded data in a dynamic mapped storage device. In a dynamically mapped storage device in which all user supplied logical blocks are dynamically mapped by the storage device controller to physical disk blocks, features and aspects hereof allow presently unused physical space to be used for storing additional metadata associated with recorded data. As the current capacity ratio of the storage device increases, appending of metadata may cease and previously recorded data including metadata may be re-recorded (migrated) to eliminate the appended metadata. The appended metadata may be used for enhanced diagnosis and analysis of characteristics of the operating storage device and may be used to restore the content of the storage device to an earlier state. The metadata may include, for example, track following position of the read/write head, temperature, head flying height, and time of day.

摘要： In accordance with various embodiments, a rotatable member is mounted to a spindle hub so that initial servo data previously provided to the rotatable member are eccentrically offset with respect to a rotational center of the spindle hub. Compensation vales are determined to characterize said offset, after which final servo data are provided to the rotatable member in relation to the initial servo data and the determined compensation values. The final servo data are nominally concentric with the rotational center of the spindle hub.

摘要： Real-time correction of repeatable runout for multiple harmonic frequencies is provided by using convolution of a position error signal, or similar real-time signal, with an impulse response of a specific transfer function, such as the inverse of the disturbance transfer function. Multiple harmonic frequencies can be followed substantially simultaneously to achieve small position error and good tracking misregistration (TMR) performance. The impulse response can be obtained, calculated and stored off-line. The impulse response can be configured to substantially eliminate correction of one or more frequency or frequency ranges. Convolution can be done relatively quickly with proper arrangement of memory.

摘要： Dynamically detecting off-track errors in a disk drive by adjusting transducer head position control parameters in response to shock events. In an embodiment, shock events with large magnitude trigger a severe shock timer which lengthens the write fault before write operations resume. In another embodiment, a lower shock threshold is used following an initial shock event. In yet another embodiment, a lower shock threshold is used if an accumulated average position error of the transducer head is large.
