摘要:
In a contact detecting apparatus that detects contact of a head with a recording medium, a signal writing unit writes onto the recording medium, a signal that includes at least one predetermined frequency component; and a contact detecting unit detects the contact of the head with the recording medium based on an amplitude of the predetermined frequency component, by reading the signal written on the recording medium while changing a spacing between the head and the recording medium.
