Abstract:
A process is disclosed for determining one or more edges of usable portions of a disk drive. Such knowledge can be used to determine the range of valid tracks of the disk and improve utilization of available disk space. The process can detect the edges by processing one or more disk controller signals, such as an adaptive feed-forward (AFC) injection signal, or a position error signal (PES).
