A data word is error correction encoded to provide a worst case codeword without bit transitions between worst case codeword bits. A modulation bit is calculated as a function of the worst case codeword. The modulation bit has a bit polarity opposite a bit polarity of the worst case codeword bits. The worst case codeword bits are added with the modulation bit to form a modulated code word.

A method is disclosed for performing a defect scan for a disk drive. Data is recorded on a first data area of a disk substantially free from defects and on a second data area of the disk substantially affected by at least one defect. A defect scan parameter is initialized with an initial setting. The first data area is read to determine a first defect threshold, and the second data area is read to determine a second defect threshold. A margin is saved representing a difference between the first and second defect thresholds. The setting for the defect scan parameter is adjusted, and the elements of reading the first and second data areas and saving a corresponding margin are repeated at least once. A setting is then selected for the defect scan parameter in response to the saved margins.

In general, this disclosure describes read recovery techniques for data storage devices that use soft information associated with multiple read operations to detect data. Specifically, the read recovery techniques comprise computing soft information for each bit detected during a first read operation of a data storage medium, computing soft information for each bit detected during a second read operation of the data storage medium and averaging the soft information computed during the first and second read operations to determine the value of each of the bits.

A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of data tracks. Data is read from one of the data tracks to generate a read signal, and a quality metric is generated in response to the read signal. When the quality metric exceeds a first threshold, a defect is detected in at least part of the data track. When the quality metric exceeds a second threshold different than the first threshold, the data track is reread to regenerate the quality metric, and when the quality metric exceeds the second threshold at least twice, the defect is detected.

A method and apparatus for selectively terminating turbo equalization is disclosed. At least two iterations of turbo equalization are performed. The number of errors corrected between the first iteration and the second iteration are calculated. In one embodiment, if the sign of corresponding bits in the data block is different between the two iterations, an error was corrected. If the number of errors corrected is greater than a stopping value, a subsequent iteration of turbo equalization is performed. If the number of errors corrected is less than or equal to the stopping value, then associated values for the data are output and the turbo equalization is terminated.

A system is provided for classifying an instruction sequence with a machine learning model. The system may include at least one processor and at least one memory. The memory may include program code that provides operations when executed by the at least one processor. The operations may include: processing an instruction sequence with a trained machine learning model configured to detect one or more interdependencies amongst a plurality of tokens in the instruction sequence and determine a classification for the instruction sequence based on the one or more interdependencies amongst the plurality of tokens; and providing, as an output, the classification of the instruction sequence. Related methods and articles of manufacture, including computer program products, are also provided.

Determining, by a machine learning model in an isolated operating environment, whether a file is safe for processing by a primary operating environment. The file is provided, when the determining indicates the file is safe for processing, to the primary operating environment for processing by the primary operating environment. When the determining indicates the file is unsafe for processing, the file is prevented from being processed by the primary operating environment. The isolated operating environment can be maintained on an isolated computing system remote from a primary computing system maintaining the primary operating system. The isolating computing system and the primary operating system can communicate over a cloud network.
