ABSTRACT:
By matching raised hard contact areas on predetermined locations of the actuator/arm/suspension assembly opposite counterpart dedicated tracks or zones, then data track damage can be avoided, otherwise resulting from shock imposed on a disk drive when the disk drive is nonoperational. Such placement permits tradeoffs among the length and power of the error correction code, and the disk area reserved to dedicated tracks or zones.
