Abstract:
1. A method for modifying magnetic information transfer, the method comprising: retrieving magnetically represented data from a storage medium; converting the magnetically represented data to a series of data samples; identifying a first preceding pattern and a first transition status in the series of data samples; determining a first current non-linear transition shift value based at least in part on the first preceding pattern, the first transition status, and a first previous non-linear transition shift value; identifying a second preceding pattern and a second transition status in the series of data samples, wherein a combination of the second preceding pattern and the second transition status is distinct from a combination of the first preceding pattern and the first transition status; and calculating a second current non-linear transition shift value based at least in part on the second preceding pattern, the second transition status, and a second previous non-linear transition shift value.
