Abstract
According to one embodiment, a measurement method is applied to a disk device including a disk, and a head configured to protrude toward the disk when power is supplied thereto. In the method, a reference value for each of areas of the disk is acquired from a measurement-value distribution including pre-measured values that correspond to power supplied to a heater when the head is brought into contact with the disk. In each area, a data group calculated from the distribution and the reference value is acquired. An area where the data group has lower values than in the other areas is selected as a first area to be firstly measured. An area to be measured subsequent to the first area based on the data group is selected.
