Abstract
According to one embodiment, a contact-detecting method includes calculating a representative value for each of a plurality of first zones. The plurality of first zones is provided at different radial locations on the disk. The representative value is calculated based on values measured at a plurality of different radial locations included in each of the first zones. The method includes detecting a contact point at which a first member contacts with a second member based on a first difference. The first difference is a difference between a value measured at an objective measuring point and a representative value of a second zone among the plurality of first zones. The objective measuring point is included in a third zone among the plurality of first zones. The second zone is arranged radially inward of the third zone.
