ABSTRACT:
Plural embedded servo sector sets are written as a single operation by a servo writer during manufacture of a hard disk drive. Later, the disk drive electronics performs a self scan and selects one good set of embedded servo sectors and erases all other sets, thereby decreasing the number of servo sector rewrites during manufacture and reducing manufacturing time and costs.
