摘要： Various illustrative aspects are directed to a data storage device, comprising one or more disks; an actuator mechanism configured to position heads proximate to a recording medium of the disks; and one or more processing devices. The processing devices are configured to detect a criterion for inserting padding on the recording medium proximate to data containers to be written to the recording medium, the containers configured for assigning logic blocks to the containers, the logic blocks configured to store data to be written in an interleaved pattern across sectors based on a distributed sector encoding scheme, wherein detecting the criterion comprises detecting a mismatch in size between at least a portion of a zone and an integer number of containers in which to write the at least a portion of the zone; and insert mapping indicators to a mapping to indicate padding blocks proximate to the containers.

摘要： Regarding 100 reels of magnetic tape cartridges in the magnetic tape cartridge group, in a case where a maximum value of an absolute value of a difference between a servo band spacing obtained before storage in a predetermined environment and a servo band spacing obtained after storage in the predetermined environment for storage time T is defined as A, an arithmetic mean of a medium lives calculated by a linear function derived from a value of A and a value of the logarithm loge T of T is 4 years or longer and 3σ is 1 year or shorter. The medium life is T in a case where A satisfies Equation 1=1.5−B, and the B is a value calculated by multiplying a difference between a maximum value and a minimum value of the servo band spacings obtained in each of the five predetermined environments by ½.

摘要： The technology disclosed herein pertains to a system and method for storing data on a storage media using both down-track super parity and cross-track super parity. Specifically, a method disclosed herein provides for generating down-track super parity values for data on the plurality of tracks and storing the down-track super parity values on a down-track super parity row of the storage block and generating cross-track super parity values for data on the plurality of rows and storing the cross-track super parity values on a cross-track upper parity track, wherein the cross-track super parity value for any given row is generated by inputting the data on the given row into an exclusive-OR (XOR) gate.

摘要： A data storage device includes a hard disk drive coupled to a printed circuit board (PCB), a volatile memory device coupled to the PCB, a non-volatile memory device coupled to the PCB, and a controller coupled to the PCB, such that the controller is in communication with the hard disk drive, the volatile memory device, and the non-volatile memory device. The controller is configured to identify patterns and/or structures of metadata for the hard disk drive, perform one or more of the following to the metadata to tailor the metadata: data shaping, content aware decoding, adaptive data trimming, and/or adaptive metablock sizing, and write the tailored metadata to the non-volatile memory device. The metadata is at least one of repeatable run out metadata, positioning error signal metadata, adjacent track interference metadata, and/or emergency power off metadata.
