Magnetic head measuring apparatus and measuring method applied to the same apparatus

Abstract

A magnetic head measuring apparatus executes measurement with respect to at least one measurement point on a recording head. The apparatus includes a probe having a magnetic substance, a vibrator which vibrates the probe above the at least one measurement point, a first signal generator which supplies a drive signal to the vibrator, a second signal generator which supplies a current containing a direct current and an alternate current to the recording head to generate a magnetic field from the recording head, a detector configured to detect a signal corresponding to a force interaction that acts on the probe due to the magnetic field generated from the recording head in accordance with the current supplied by the second signal generator, and a measurement unit which measures current dependence of the magnetic field of the recording head from the signal detected by the detector.
