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, the process proceeds to step (2), otherwise the process proceeds 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 method for reducing skew angle variation range in a shingled magnetic recording system, the method comprising the following steps:
1) determining whether a starting magnetic track is in an inner recording zone, if yes, the process proceeds to step (2), otherwise the process proceeds to step (4); 2) using an inner writing corner to start shingled magnetic recording at a starting track, the process then proceeds to step (3); 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, until all the information needing to be written into the inner recording zone has been recorded; 4) determining whether the starting magnetic track is in the outer recording zone, if yes, the process proceeds to step (5); 5) using an outer writing corner to start shingled magnetic recording at the starting track, the process then proceeds to step (6); and 6) using the shingled magnetic method to write the rest magnetic tracks sequentially by the outer writing corner, keeping the writing pole moving in a direction from the outer recording zone to the inner recording zone, until all the information needing to be written into the outer recording zone has been recorded. |
