摘要:
A recording system stores recording cycle information identifying the parameters for recording user data on a particular data sector. During a subsequent operation, the recording system employs the recording cycle information to select a different set of parameters for recording new user data at the particular data sector. One of the parameters might identify a recorded pattern in a balance pad at the data sector, and another one of the parameters might identify a scrambler seed value. By employing a different set of recording parameters for each occurrence of recording user data at the particular sector, sample timing of, for example, a read channel might be based on an average of easy and hard transitions.
