Abstract:
1. An apparatus comprising: a recording medium having media dots that are separated from each other by regions of non-magnetic material, each media dot being associated with a timing window, and each region of non-magnetic material being associated with an error window; and a device configured to saturate a writing element within each of the timing windows and configured to de-saturate the writing element within each of the error windows, wherein the device is further configured to saturate the writing element by generating a same polarity magnetic field in the writing element during substantially entire time durations of consecutive ones of the timing windows corresponding to at least two adjacent ones of the media dots and configured to de-saturate the writing element within an error window between the consecutive timing windows for a time duration that is substantially smaller than a time duration of an individual one of the consecutive timing windows.
