Various systems and methods for peak signal detection. As one example, a method for peak signal detection that includes receiving a signal is disclosed. The received signal includes a signal region where the signal is increasing in amplitude, another signal region where the signal is decreasing in amplitude, and a transitional signal region coupling the first two signal regions. In some cases, the transitional region is of zero duration and the signal transitions directly from the increasing region to the decreasing region. The method further include calculating a distance between the signal region of increasing amplitude and the signal region of decreasing amplitude, and determining a peak of the received signal that is one half the distance from the signal region of increasing amplitude.

A recording system records sector information on a recording medium, such as a hard disc drive, using a write gate signal. Timing of the write gate signal enables writing a servo data patterns over the servo wedge fields of the disc and, if the hard disc drive contains prior recorded data, writing null data over selected sector segments of the hard disc.
