  • Data storage system with late read buffer assignment after arrival of data in cache
    Patent number: 11294572
    Abstract: A data storage system may have a number of data storage devices that each have a non-volatile memory connected to different first and second memory buffers. A data storage device can consist of a non-volatile memory where a data sector is stored. A network controller can consist of a buffer module connected to a first memory buffer and a second memory buffer that receives a data read request from the host for the data sector and evaluates the first and second memory buffers as a destination for the data sector after the data sector arrives at the buffer module. The buffer module may choose the first memory buffer and store the data sector in the first memory buffer prior to providing the data sector to the host to satisfy the data read request from the first memory buffer.

  • Method and apparatus for modulating a laser power signal during heat-assisted magnetic recording
    Patent number: 11270733
    Abstract: A disk drive apparatus determines a pattern of bits of a data signal applied to a magnetic write transducer of a heat-assisted magnetic recording apparatus. The magnetic write transducer applies a magnetic field to a recording medium in response to the data signal. A laser power signal is applied to a laser that heats the recording medium while the magnetic field is applied. The laser power signal is modulated based on the pattern of bits. The modulation reduces differences between track widths of recorded marks having different elapsed time values and/or increases a signal-to-noise ratio of the recorded marks having different elapsed time values.
