METHOD FOR REDUCING VARIATION RANGE OF SKEW ANGLE OF MAGNETIC WRITING POLE AND MAGNETIC WRITING POLE USING THE METHOD

摘要

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.

1. A magnetic writing pole for reducing a skew angle variation range in a shingled magnetic recording system, the magnetic writing pole comprising:
an inner writing corner; and an outer writing corner,wherein:
an angle α1 of the inner writing corner is of the value between 50° and 120°; and an angle α2 of the outer writing corner is of the value between 50° and 120°.
