Abstract
According to an embodiment, a controller of a magnetic disk apparatus performs a write operation. In the write operation, the controller performs interpolation using RRO correction values that is obtained by measurement RRO at multiple first positions, and thereby acquires an RRO correction value for performing RRO correction at a position of a target data track. In the write operation, the controller sets WOS on the basis of a write permissible range change determination distance that is a distance between the target data track and one of the multiple first positions that is closest to the target data track.
