<p>A disk drive 800 has at least one disk with a major disk surface that includes a first region 820 including a plurality of tracks 823 and a second region 830 including a plurality of tracks 832. The first and second regions are separated by a guard band 810. The track or tracks 829, 831 near the guard band have a track width that is greater than the track widths of the tracks more distant from the guard band, such as those in the middle of the first and second regions as this reduces the occurrence of far track interference. The tracks on the disk surface may be organized into a plurality of shingled regions (I-regions) 820, 830, 840 where writing information includes overwriting a portion of a previously written track. The amount of overwriting may be dynamically variable depending on an environmental stability indicator from an environmental monitor which may be a vibration detection unit.</p> |
