Abstract

In a magnetic disk drive the integrity of data written on a disk is ensured by writing data to a portion of the disk (30) and, simultaneously detecting the presence and/or the frequency of TI (thermal interference) (34) events. If either is detected an error c ondition is generated. The error condition may be reporting the error to the host which decides whether to rewrite the data or immediately rewriting the data without further instructions from the host.
