A disk drive includes a data storage disk that has servo information thereon which includes first servo bursts and second servo bursts. The first servo bursts are at least substantially radially aligned with each other, and have low frequency regions therebetween. Adjacent ones of the low frequency regions between the first servo bursts have magnetic polarities that are opposite to one another. The second servo bursts are at least substantially radially aligned with each other and have low frequency regions therebetween. The first and second servo bursts are in a single servo region.
