ABSTRACT:
Provided is a thin-film magnetic head for reading data from a magnetic recording medium and/or writing data to a magnetic recording medium, in which the magnetic spacing can be controlled appropriately by stably adjusting the pressure working between the thin-film magnetic head and the magnetic recording medium according to the change of conditions such as the change over time. This thin-film magnetic head comprises at least one through hole reaching a surface opposed to the magnetic recording medium of the thin-film magnetic head, for adjusting a pressure working between the thin-film magnetic head and the magnetic recording medium. Preferably, the head further comprises at least one flow-amount control means for controlling the flow amount of gas that flows via the at least one through hole.
