摘要：
A memory device, includes a recording medium; a probe to write a plurality of the signals; a first driving portion to vibratory drive the recording medium; a detecting unit which, when the first driving portion changes a frequency to vibratory drive the recording medium, detects a change in an amplitude of the resonance drive, detects the frequency at which the amplitude becomes maximum as a resonance frequency; and a calculating unit which calculates a timing when the probe writes a plurality of the signals using the resonance frequency; wherein, the first driving portion vibratory drives the recording medium and the probe writes a plurality of the signals.
