Abstract
Systems, methods, and firmware for operating data storage devices and storage processors are provided herein. In one example, a data storage device is provided. The data storage device includes magnetic storage media configured to store data, read heads configured to read data from the magnetic storage media at associated areal densities, and a storage processor. The storage processor is configured to monitor read error rates of the read heads during operation of the data storage device to identify a degraded one of the read heads, and process at least the read error rates and an areal density of the degraded one of the read heads to modify the areal density of at least the degraded one of the read heads.
