  • Patent number: 10068597
    Abstract: First tracks of a disk are read via a first read transducer. The first read transducer has a first crosstrack width and a first shield-to-shield spacing that are optimized to read a first track width and a first linear bit density of the first tracks. Second tracks interlaced between the first tracks are read via a second read transducer. The second read transducer has a second crosstrack width different from the first crosstrack width and second shield-to-shield spacing different than the first shield-to-shield spacing. The second crosstrack width and the second shield-to-shield spacing are optimized to read a second track width different from the first track width and a second linear bit density different from the first linear bit density.

  • Patent number: 10026443
    Abstract: An error is determined in a target track of a heat-assisted recording medium. The error triggers an error recovery procedure. The error recovery procedure involves storing data from at least part of an adjacent track that is immediately proximate the target track to another data storage location. The error recovery procedure also involves, for two or more iterations in which a laser power is incrementally changed from a lower power to a higher power, erasing at least part of the adjacent track at the laser power and attempting to recover the target track.

  • Patent number: 9971913
    Abstract: A circuit may be configured to adaptively combine two or more waveforms into a single waveform. The circuit can generate weighting factors based on received error signals, and can apply the weighting factors to the two or waveforms to be combined. In some examples, a circuit can be configured to receive input signals, receive error signals, generating a weighting coefficient based on at least some of the error signals, and determine an output signal based on the weighting coefficient and the input signals.

  • Patent number: 9928872
    Abstract: In a method, read signals from each of a plurality of read transducers of a data head are buffered for each of a plurality of cross-track positions of the head relative to a data track. The buffered read signals are processed to establish a quality metric for each of the read signals and at least one combination read signal comprising at least two of the read signals. A data recovery cross-track position and a reader configuration comprising one or more of the read transducers are identified based on the quality metrics. A data read operation is then performed with the data head in the data recovery cross-track position using the read signals from the identified reader configuration.

  • Patent number: 9830942
    Abstract: First and second different write precompensation values are associated with different first and second non-return-to-zero, inverted (NRZI) data patterns. The first and second different write precompensation values cause a predetermined phase shift to be written into test data that comprises the first and second NRZI data patterns. The test data is mitten to a recording medium of a storage device using the first and second write precompensation value. The test data is used to determine a response of the storage device to the predetermined phase shift.

  • Patent number: 9489976
    Abstract: Technologies are described herein for adapting channel parameters of a read channel in a transformed space. A set of channel parameter values associated with one or more components of the read channel is received. A general transformation is performed on the channel parameter values, and insignificant terms in the transformed space are filtered out. Next, an inverse transformation is performed on the filtered terms in the transformed space to calculate a new set of channel parameter values for the component(s).

  • Patent number: 9099158
    Abstract: Certain exemplary aspects of the present disclosure are directed towards an apparatus in which a data-access head is used to access a sequence of data stored in adjacent ones of multiple tracks of a data-storage device, where the sequence of data includes a stochastic or pseudo-random set of bits and on an adjacent one of the multiple tracks, the sequence of bits is represented in a phase-shifted form. The data access of the multiple tracks bits is used to characterize nonlinear interaction therebetween.
