摘要:
Systems and methods for synchronizing write signals are disclosed. In one embodiment, a compensation system is implemented within a disk drive that receives a synchronization signal read from a patterned magnetic disk by a read head. The compensation system processes the synchronization signal to compensate for noise sensed by the read head while a write head writes to the disk based on a write signal. The adjustment module is operable to adjust the write signal based on the processed synchronization signal so that the write signal is synchronized to the pattern on the disk.
