Far field interference mitigation by relative frequency ordering

Far field interference mitigation by relative frequency ordering

A method is disclosed for improved operation of a data storage device such as a hard disk drive, wherein the overhead for data rewriting is reduced or eliminated by the grouping of logical zones in proximity to other zones with similar writing frequencies. Thus cold zones are written near other cold...

description A method is disclosed for improved operation of a data storage device such as a hard disk drive, wherein the overhead for data rewriting is reduced or eliminated by the grouping of logical zones in proximity to other zones with similar writing frequencies. Thus cold zones are written near other cold zones, and hot zones near other hot zones, within a multiplicity of realms on the data storage surface. Substantial reductions in FTI writes are achievable in comparison with previous FTI mitigation algorithms.
