Abstract
Methods, apparatuses and systems for detecting defective sectors on a recording medium, the method including calculating a servo gain for each servo sector of a track of a recording medium of a storage device; determining whether the servo gain of each servo sector exceeds a threshold value; and upon determining that the servo gain of a servo sector exceeds the threshold value, determining data sectors included in the servo sector to be defective sectors.
