Abstract: A method includes partitioning a received data chunk into first and second data sectors to be stored in respective first and second store units. The method also includes generating first and second random keys. The method further includes encrypting the first data sector with the second random key, and encrypting the second data sector with the first random key. The first and second random keys are encoded with channel codes. Thereafter, the first encoded random key is appended to the first encrypted data sector to obtain first appended data, and the second encoded random key is appended to the second encrypted data sector to obtain second appended data.

Abstract: Systems and methods are disclosed for improving data channel design by applying transform domain analytics to more reliably extract user data from a signal. In certain embodiments, an apparatus may comprise a channel circuit configured to receive an analog signal at an input of the channel circuit, and sample the analog signal to obtain a set of signal samples. The channel circuit may further apply a filter configured to perform transform domain analysis to the set of signal samples to generate a first subset of samples, the first subset including fewer transitions and having a higher signal to noise ratio (SNR) than the set of signal samples. The channel circuit may detect first bit transform domain representation values from the first subset, and determine channel bit values encoded in the analog signal based on the set of signal samples and using the first bit transform domain representation values detected from the first subset as side information.

Abstract: Bottom tracks are written to a recording medium using a first setting of a spin-torque oscillator of a single microwave assisted magnetic recording (MAMR) head. Top tracks are written interlaced between and partially overlapping the bottom tracks using the single MAMR head at a second setting of the MAMR head, the first and second settings resulting in different bit aspect ratios for the top and bottom tracks.

Abstract: Two or more read modes of a data storage system and device are defined. The data storage device is capable of concurrently reading from two or more tracks using two or more read transducers. The read modes utilize different numbers of the two or more read transducers while reading data. The read modes are selected based on an operating condition of the data storage system or device.

Abstract: A recording head has a first magnetic writer and a second magnetic writer offset from the first magnetic writer in a downtrack and crosstrack direction. The recording head has leads configured to deliver respective first and second write and/or laser currents to the first and second writers. The first and second write and/or laser currents enable the first and second writers to simultaneously write to adjacent tracks of a magnetic disk.

Abstract: Host data to be written to a recording medium is categorized as one of sequential data or random data. The sequential data is written to a first track width on the recording medium. The random data is written to a second track width on the recording medium, the second track width being larger than the first track width.

Abstract: Features are detected from a sensor signal via a deep-learning network or other feature engineering methods in an edge processing node. Machine-learned metadata is created that describes the features, and a hash is created with the machine-learned metadata. The sensor signal is stored as a content object at the edge processing node, the object being keyed with the hash at, the edge processing node.
