  • Patent number: 8937779
    Abstract: A method for reducing skew angle variation range in a shingled magnetic recording system, the method including the following steps: 1) determining whether a starting magnetic track is in an inner recording zone; if yes, proceeding to step 2), otherwise proceeding to step 4); 2) using an inner writing corner to start shingled magnetic recording at a starting track; 3) using a shingled magnetic method to write rest magnetic tracks sequentially by the inner writing corner, keeping a writing pole moving in a direction from an inner recording zone to an outer recording zone; 4) determining whether the starting magnetic track is in the outer recording zone; 5) using an outer writing corner to start shingled magnetic recording at the starting track; and 6) using the shingled magnetic method to write the rest magnetic tracks sequentially by the outer writing corner.
