    Abstract: A readback signal from a first reader and a readback signal from a second reader are received, the first reader and the second reader configured to read two-dimensional data from at least one track of a recording media. A quality metric of the second reader is measured based on the readback signal. It is determined if the quality metric for the second reader is above a threshold. If the quality metric is above the threshold, the first reader and the second reader are used to read the data.

    Abstract: Apparatus and method for light source power control during the writing of data to a storage medium. In accordance with various embodiments, a data recording head is provided having a magnetic transducer and a light source. The light source is driven at a first power level to irradiate an adjacent storage medium prior to the writing if data to the medium using the magnetic transducer. The first power level is insufficient to alter a magnetization state of the medium. The light source is subsequently transitioned to a higher, second power level to irradiate the storage medium during the writing of data to said medium using the magnetic transducer, the second power level being sufficient to alter said magnetization state of the medium.

    Abstract: A data storage apparatus includes a disk storage region in which magnetic disks are stored. A carrier mechanism picks up one or more of the magnetic disks and moves them to and from the disk storage region. A data access device of the apparatus includes a structure to receive the one or more magnetic disks from the carrier mechanism and spins the magnetic disks in place. One or more actuator arms are operable to move across a same surface of the one or more magnetic disks. Two or more read transducers are mounted to the actuator arms and operable to simultaneously read from the same surface of the one or more magnetic disks. Two or more write transducers are mounted to the actuator arms and operable to simultaneously write to the same surface of the one or more magnetic disks.

    Abstract: A data storage device includes a data storage medium having a data storage surface. The data storage device also includes a first actuator having a first attached slider with a writer configured to write data on the data storage surface. The writer has a media-confronting surface covered by a first non-magnetic overcoat having a first thickness. The data storage device further includes a second actuator having a second attached slider with at least one user-data reader configured to read user data from the data storage surface and no writer for writing data on the data storage surface. The at least one user-data reader has a media-confronting surface covered by a second non-magnetic overcoat having a second thickness that is less than the first thickness of the first non-magnetic overcoat.

    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.
