OTER vs write phase and track write offset for (a) , (b) , and (c) . The write phase is normalized by the bit length and the data is parsed in 0.05 bit intervals. A lack of data points indicates that no errors were recorded when writing at the specified write phase. The error bars represent 1-sigma statistical uncertainty. The dotted lines are fits of the OTER at zero track offset using Eq. (1). The shifting of the OTER curves with track offset originates from the curvature of the head fields at the edge of the writer.

Magnetic read-back image showing patterns consisting of written at (a) , (b) , and (c) . The blurred features seen in between the island signal in [(a) and (b)] originates from trench domains (Ref. 10).
