Systems and Methods For Burst Demodulation

A method for demodulating a servo data burst field, comprising:

• calculating a burst integration result for each half-cycle of the burst field;
• accumulating the burst integration results for each half-cycle of the burst field to produce a position error signal;
• determining whether an absolute value of the burst integration result for each half-cycle of the burst field is outside a window;
• and
• flagging a media flaw when an absolute value of the burst integration result for any half-cycle of the burst field is outside the window.

A storage device, comprising:

• a storage medium;
• a head assembly disposed in relation to the storage medium and operable to provide a sensed signal corresponding to a data set on the storage medium;
• and
• a read channel circuit including a burst demodulator, comprising:
• a burst integration circuit operable to calculate burst integration results for a servo data burst field in the data set;
• a comparison circuit operable to determine whether an absolute value of the burst integration results falls outside a window;
• and
• an error indicating circuit operable to indicate that a media flaw has been detected when the absolute value of the burst integration results fall outside the window.
