Abstract
Read and write transducer elements have very high reliability for most of their respective lives. Only a small percentage of transducer elements fail after a significant duration of operation in the field, but failure rate ramps up significantly with as the transducer elements age, particularly with heavy read and write use. Prior solutions to this problem involve regularly running data field integrity checks. However, the data field integrity checks are resource intensive and yield significant latency impacts. The presently disclosed technology renders data field integrity checks (that come with high latency costs) dependent upon periodic or continuous head health monitoring schemes (that come with low latency costs). The data field integrity checks are triggered by a 'poor health' signal generating from the head health monitoring schemes rather than being continuously or periodically performed with no regard to projected head health.
