Abstract
First tracks are read via a first head that is moved via a first actuator over a first, radially-defined, zone of a disk surface. Second tracks are read via a second head that is moved via a second actuator over a second zone of the disk surface that is separate from the first zone. The first and second heads are optimized to read data within first and second skew angle ranges associated with the first and second zones. The first and second skew angle ranges are each less than a total skew angle range of the disk surface.
