Abstract: The presently disclosed technology teaches integrating disc drive electronics into a transducer head. Decreased electrical transit times and data processing times can be achieved by placing the electronics on or within the transducer head because electrical connections may be made physically shorter than in conventional systems. The electronics may include one or more of a control system circuit, a write driver, and/or a data buffer. The control system circuit generates a modified clock signal that has a fixed relation to phase and frequency of a bit-detected reference signal that corresponds to positions of patterned bits on the disc. The write driver writes outgoing data bits received from an external connection to off-head electronics directly to the writer synchronized with the modified clock signal. The data buffer stores and converts digital data bits sent from the off-head electronics to an analog signal that is synchronized with the modified clock signal.

Abstract: An adaptive guard band for a ramp load/unload device is disclosed to provide extended data storage. In illustrated embodiments, an adaptive guard band algorithm is configured to format one or more discs or media having a lower capacity device with the adaptive guard band and extended data zone utilizing capacity measurements. The algorithm formats the media to provide a track zero at a first cylinder if the capacity is at or above the threshold capacity and a second cylinder if the capacity is below the threshold capacity to provide the extended data storage zone. A size or width of the extended data zone is variable to provide additional capacity to meet the threshold capacity.

Abstract: A method or system comprising iteratively updating a value of an operating parameter of a storage region of a storage device based on dynamic characterization of the storage region during operation of the storage device and using the updated value of the operating parameter during access to the storage region.

Abstract: Values are grouped into a first set of groupings of values. Based on inner codes, the number of groupings in the first set of groupings that have at least one erroneous value is determined. If the number of groupings in the first set of groupings that have an erroneous value is fewer than a maximum number of groupings that can be corrected by outer codes, a seek operation is begun. During the seek operation, the outer codes are used to detect and correct the erroneous values that were produced during the reading of values. In other aspects, a parity section for a data section of a data storage device is dirtied before writing any data to the data section such that if writing to the data section is interrupted, the parity section will indicate that it should not be used to correct data read from the data section.

Abstract: A predictive failure control circuit and associated method are provided in a data storing and retrieving apparatus. The circuit is configured to schedule a data integrity operation on data associated with a subportion of a data storage space, in relation to a comparison of an accumulated plurality of executed host access commands associated with the subportion. The subportion can comprise a sector or a single track or a band of tracks. A table preferably stores accumulated number of host access commands for each of a plurality of subportions of the data storage space. The data integrity operation can comprise reading the data on to detect degradation and restoring the recovered data to the same or to new, different tracks. The data subportions can also be reallocated to a new location.
