摘要：Embodiments of the present invention help to increase the capacity and the
reliability of a disk drive device to improve the manufacturing yield thereof. Anembodiment of the present invention sets a data track pitch for each head slider
(recording surface) in accordance with head characteristics. This method for specifying thedata track pitch is based on the distance between erase band ends (EBEs) of the bothadjacent data tracks. The erase band of a data track is a band defined as the area wherethe already written data are erased in writing the data track. The distance between theerase band ends of the both adjacent data tracks corresponds to the width SW of thearea which is not erased by the adjacent data tracks. Specifying the data track pitch basedon this leads to increase in the data capacity of each recording surface and secureprevention of occurrence of a squeeze error.
