ABSTRACT:
A method of measuring a flying height of a thin-film magnetic head, capable of measuring the flying height without using a new component, such as an atmospheric pressure sensor, which is adverse to a requirement of reduction in cost and size. The method of measuring a flying height includes causing a thin-film magnetic head including a read head element receiving a signal magnetic field from a magnetic disk to contact the rotating magnetic disk temporarily; and measuring a flying height of the thin-film magnetic head by measuring outputs from the read head element at a time of the contact and during flying of the thin-film magnetic head.
