Abstract:
According to one embodiment, a magnetic disk device, includes a disk including a track including a plurality of servo sectors, a head including a write head which writes data to the disk and a plurality of read heads which read the data from the disk, and a controller configured to simultaneously acquire a plurality of pieces of correction data for repeatable runout of the disk by the read heads, acquire a first correction data and a second correction data based on the correction data, write the first correction data and the second correction data to the disk, and correct a position of the head based on the first correction data and the second correction data.

Claim (Index 4):
The magnetic disk device according to  claim 1 , wherein the controller is configured to acquire a third correction data at a third position by a first read head used for positioning of the head among the read heads, acquire a fourth correction data at a fourth position by a second read head which is not used for the positioning of the head among the read heads, correct the fourth correction data to a fifth correction data, calculate the first correction data based on the third position, the fourth position, the third correction data, the fifth correction data and the first position, and calculate the second correction data based on the third position, the fourth position, the third correction data, the fourth correction data and the second position.
