Abstract
A method for sampling a current track and an adjacent track of a storage medium includes using a first read head to read a first data stream from the current track, using a second read head to read a second data stream from the adjacent track, delaying one of the first and second data streams to account for a position difference between the first and second read heads, and controlling sampling of the first and second data streams to align the first and second data streams. Controlling the sampling may include applying a synchronous sampling signal to control the first and second read heads so that they sample at synchronous locations, or may include sampling the current and adjacent data tracks at asynchronous locations and interpolating the first and second data streams to provide aligned samples. A storage device may operate in accordance with the method.
