Abstract
Write-through media caching for a Data Storage Device (DSD) including at least one disk for storing data. A write command is received for storing data in the DSD and the data is written for the write command in a first region of the at least one disk with a first track density. The data for the write command is also written in a second region of the at least one disk with a second track density greater than the first track density without reading the data for the write command from the first region.
