ABSTRACT:
The method of testing a magnetic head is capable of purely evaluating characteristics of the magnetic head without influences caused by external factors. The method of testing a magnetic head comprises the steps of: detecting amount of noises, which are included in output signals of a reading element of the magnetic head, a plurality of times in a state of reading no magnetic data; and comparing an amount of variation between the detected amounts of noises with a threshold value.
