摘要： Methods and structures for providing on-the-fly head depopulation in a dynamically 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 on-the-fly head depopulation to protect data when a subsection of a storage device, such as a head of surface is failing. When the storage device detects that a head is failing, data may be migrated off the failing subsection into other subsections (e.g., a different head or surface) using mapping features and aspects hereof. Thus, the data on the failing subsection is still available should the subsection or head eventually fail.

摘要： Methods and structures for performing field flawscan to reduce manufacturing costs of a dynamic mapped storage device. In a dynamic 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 permit flawscan testing of a storage device to be completed substantially concurrently with processing write requests for its intended application. A fraction of the storage device may be certified by an initial flawscan performed during manufacturing testing. Statistical sampling sufficient to assure a high probability of achieving specified capacity may be performed to reduce manufacturing time and costs in testing. Final flawscan of the remainder of the storage locations may be performed substantially concurrently with processing of write requests after the device is installed for its intended application. Mapping features and aspects hereof allow the storage device controller to perform flawscan and write operations concurrently.

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： Methods and structures for dynamic density control to improve reliability of a dynamically 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 provide for dynamically altering the recording density of user data stored on the storage device. So long as the physical capacity utilization of the storage device permits, new data stored on the device may be stored at lower density to improve reliability in reading back the recorded data. Further features and aspects hereof may reduce the recording density only for data deemed to be critical. Radial (track) density, longitudinal (bit) density, or both may be dynamically controlled to reduce recording density. As physical capacity utilization increases, data previously recorded at lower density may be migrated (re-recorded) at normal higher density.

摘要： Methods and structures for writing thermal lead-in sequences to provide head stability in a dynamically 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 provide writing thermal lead-in sequences to allow the write head to stabilize. As the write head begins writing a sequence of data to the recordable media, the write head may not have a desired thermal stability. Thus, there may be thermal flux with some of the data, affecting the reliability of the data. Mapping features and aspects hereof allow the write head to write a thermal lead-in sequence of data that does not destroy valuable data, allowing the write head to begin writing before stabilizing. Writing the thermal lead-in sequence will cause the write head to warm up and become stable, and thus be ready to write valid data.

摘要： Methods and structures for dynamic multiple indirections to improve reliability and performance of a dynamically mapped storage devices. 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 provide for dynamically altering the number of replicated copies (multiple mapped indirections) of user data stored on the storage device. Performance information regarding operation of the storage device may be gathered by the storage device controller such that where physical capacity of the storage device permits and as degrading reliability is detected, additional copies (multiple indirections) of stored user data may be written to the mapped storage device. Increased multiple indirections improves reliability by decreasing the probability of data loss in response to various failure modes of the storage device. Strategic physical placement of the multiple copies (multiple indirections) may improve performance by reducing latencies associated with accessing the user data.

摘要： Methods and structures for recovering from an off-track position error in a dynamically mapped storage device. In a dynamically mapped storage device data is dynamically mapped to a physical location on the recordable media. Thus, when a write fault occurs, such as an off-track position error, the data may be re-written and re-mapped at a different location on the recordable media. In a dynamically mapped storage device data may be reordered into a sequential stream of contiguous physical data blocks. Random host data blocks may be mapped into sequential physical data blocks on the recordable media. Further, the sequential reordering of the data blocks may ensure that no data is present in tracks or sectors directly ahead of the track of sector being written. Further, the system has the ability to store multiple revolutions of host supplied data within the disk drive memory buffer and maintain the information in memory while writing it to the recordable media. The multiple revolutions of host supplied data may be used to recover from the destruction of previously written physical blocks overwritten during an off-track position error.

摘要： The invention relates to a disk drive servo apparatus, and method for implementing the same, that maintains a transducer on a substantially non-perturbed path despite the fact that the tracks were written in a perturbed manner by a servo track writer. The invention utilizes a non-causal filter to determine servo track writer repetitive run-out (STW.sub.-- RRO) values for each sector of each track at the drive level. The STW.sub.-- RRO values are stored, preferably in their respective servo sectors on the surface of the disk, for use during track following operations. During read and write operations, the STW.sub.-- RRO values are retrieved from storage and are used to generate position error signals necessary to maintain the transducer on the desired path.

摘要： In one embodiment, an encoder reads a set of data from memory cells to obtain retrieved data influenced by one or more distortion mechanisms as a result of having been stored. A quality metric is generated responsive to the retrieved data that changes in value responsive to differences between the user data and the associated retrieved data. A quality monitor establishes a relationship between a current value of the quality metric and a threshold value and monitors the relationship as being indicative of a degradation of the quality of the retrieved data, and selectively initiates an error response. In another embodiment, a correction value is iterated through a set of values as a quality metric is monitored such that the value of the quality metric which most closely approaches the value of the quality metric immediately subsequent to an initial writing of the data can be selected.
