Abstract

Managing data stored in a Data Storage Device (DSD) including at least one disk for storing data. Data is written in a first region of the at least one disk with a first track density. A frequency of access is determined for the data written in the first region, and the frequency of access is compared to a threshold. Based on the comparison, a copy of the data written in the first region is written in a second region of the at least one disk with a second track density different than the first track density.
