|Abstract:||The hard disk drive (HDD) industry continues to meet the ever growing demand for storage capacity by increasing both the number of tracks on the disk surface and the number of bits recorded per track. Sensing of the position error signal (PES) plays a very important role in the precision and accuracy achieved by the track-following servomechanism. Need for better sensing of PES made the researchers explore different techniques of servo encoding dual frequency servo burst being one of them. This paper addresses different aspects of decoding PES from these servo bursts. An algorithm based on Discrete Fourier Transform (DFT) is used. Claims are supported by both simulation and experimental data.|
