Abstract
Methods for making a disk drive, apparatus for writing servo bursts on a disk, and disk drive apparatus are provided. The disk drive includes a disk and transducer adjacent to the disk. The transducer includes a read element and a write element. A width of the read element is determined. A servo track pitch is determined based on the read element width. Servo bursts are written in servo tracks on the disk with the write element based on the servo track pitch.
