Abstract:
Bits are written to a track of a heat-assisted magnetic recording medium via a write transducer at a first skew angle. The track is read via a read transducer oriented at a second skew angle different from the first skew angle. The second skew angle causes the read transducer be more closely aligned with boundaries of the bits than if oriented at the first skew angle.
