    摘要： A storage apparatus capable of measuring the vibration of a head vibration having a high frequency includes: a gate generation section that generates a plurality of first gate signals indicating the timing at which the head reads out servo information having a waveform for measurement of a reproduction signal level from a storage medium on which the servo information is written at predetermined intervals and on a first track of which a first waveform serving as a waveform for measurement of a reproduction signal level is written and which is at least a predetermined track and a second gate signal indicating at least one timing between the first gate signals; and a measurement section that measures the reproduction signal level of the waveform for measurement reproduced by the head at the timing of the gate signals.
