Abstract
Various illustrative aspects are directed to a data storage device, comprising one or more disks; an actuator arm assembly comprising one or more heads, and configured to position the one or more heads proximate to disk surfaces of the one or more disks; and one or more processing devices. The one or more processing devices are configured to detect one or more physical defects on a recording medium; designate, in a mapping of the recording medium, the one or more physical defects for exclusion from being assigned to data containers, the data containers configured for assignment of a plurality of logic blocks to the data containers, the logic blocks configured to store the data to be written that are being interleaved across a plurality of sectors based on a distributed sector encoding scheme; and designate one or more artificial defects adjacent to the one or more physical defects for exclusion from being assigned to the data containers in the mapping.
