A method and apparatus for improving the settle time and thus, the transition
from
seek control to track following control in a disc drive system are provided. With
the apparatus and method, two counters are provided-a consecutive counter and a
non-consecutive counter. The consecutive counter counts consecutive samples that
meet threshold requirements. The non-consecutive counter counts non-consecutive
groups of consecutive samples that meet threshold requirements. When the consecutive
counter reaches a first predetermined value, the non-consecutive counter is incremented
and the consecutive counter is reset to zero. When the non-consecutive counter
reaches a second predetermined value, a track following control mechanism is initiated
to thereby transition from a seek control operation to a transitional control operation
and finally a track following control operation.
