摘要：
A method for measuring a variation in the floating amount of a magnetic head comprising: measuring the ambient temperature which is a temperature of the magnetic storage apparatus; reading a signal recorded in the magnetic recording medium; measuring a signal value which is a value related to a signal read in the reading; and calculating a variation in the floating amount of the magnetic head based on relationship information which is information representing a relationship between the ambient temperature and signal value that have previously been measured, measurement value which is the ambient temperature measured in the measuring of the temperature, and signal value measured in the measuring of the signal.
