Abstract
Methods, systems and computer program products for launching one or more reference spiral sets using different tracks are described. In some implementations, a method can be used that includes writing a first spiral set starting at a first track and determining a radial offset. Then a second track is determined based on the radial offset. A second spiral set is also written starting at the second track. A spiral set-to-wedge ratio is determined based on a number of spiral sets to be written. Subsequently, servo information can be written using the first spiral set and the second spiral set. The servo information can include one or more sets of servo wedges, which can be written based on the spiral set-to-wedge ratio.
