Abstract
A method for detecting servo data and an interleaved dibit detection apparatus are provided for servo data detection in a direct access storage device. The interleaved dibit detection apparatus includes a new dibit threshold detector for detecting a predefined threshold level of a new interleave servo signal and providing a new detected dibit output. An old dibit threshold detector detects the predefined threshold level of an old interleave servo signal and provides an old detected dibit output. A combining function coupled to the new dibit threshold detector and the old dibit threshold detector provides a combined detected dibit output.
