  • Partial adjustment of disk drive areal density to compensate for head or surface degradation
    Patent number: 11430471
    Abstract: A disk drive is operable to determine degradation associated with writing to a disk surface by a head which has written existing data at a first areal density. A second areal density less than the first areal density is determined that remediates the degradation. The disk drive performs subsequent writes to the disk surface at the second areal density, and continues to read the existing data at the first areal density.
