Multiple sector reassign on write error for disk drive

摘要

A disk drive includes a disk for storing information representing data, and a memory device. A method for writing includes locating a first data sector on a disk where a write operation fails, identifying the first data sector and a plurality of other data sectors near the first data sector as a grown defect, and storing the location of the first data sector and the plurality of other data sectors on a grown defect list. The memory device includes a list of grown defects that identifies a plurality of data sectors stored along a track between the first servo wedge and the second servo wedge on a selected track as data sectors which may not be written to.
