Abstract
Various systems and methods for accessing data via a variable polarity head assembly are disclosed herein. As one example, a method for accessing data is disclosed that includes receiving a data set, and sampling the data set using positive synchronization to create one data set and negative synchronization to create another data set. A respective sync mark is identified in each of the data sets, and the identified sync marks are compared. Based at least in part on the comparison of the sync marks, a polarity of the data set is identified. Based on the determined polarity of the data set, the data set may be delivered in a known polarity.
