A data storage system in which multiple readback signals are resolved is
provided. The data storage system includes a data storage medium
configured to store servo marks and data marks. The data storage medium
has tracks that are divided into sectors. An array of heads is configured
to interact with the data storage medium. A demodulation circuit receives
servo signals obtained by at least some heads of the array of heads and
computes a resultant servo signal, which is used to adjust a position of
the array of heads over the storage medium.
