Abstract:
According to one embodiment, a magnetic disk device includes a disk, a head that writes data to the disk and reads data from the disk, and a controller. The controller is configured to read first data written on the disk, measure a first read error rate of the first data, determine a difference in the first read error rate from a previously determined read error rate of the first data, determine a current read error rate for second data written on the disk based on the difference in the first read error rate from the previously determined read error rate, and determine whether a refresh process is performed on the second data based on the current error rate.

Claim (Index 1):
A magnetic disk device comprising:\n a disk; a head that writes data to the disk and reads data from the disk; and a controller configured to:\n read first data written on the disk; \n measure a first read error rate of the first data; \n determine a difference in the first read error rate from a previously determined read error rate of the first data; \n based on the difference in the first read error rate from the previously determined read error rate, determine a current read error rate for second data written on the disk; and \n based on the current error rate, determine whether a refresh process is performed on the second data.
