Abstract
A rotary head cleaning apparatus and method is disclosed, in which a control unit reserves recording times and operates a cleaning mechanism based on time information from a clock that measures time-of-day. The rotary head cleaning apparatus operates the cleaning mechanism when the time determined by the clock coincides with a non-reserved time other than times reserved for recording.
