Abstract: PURPOSE: To accurately record a control signal in a fixed period by giving a low level signal to a control head when a 1st counter becomes a 1st prescribed value and the 2nd counter becomes a 2nd prescribed value in their count. CONSTITUTION: When a capstan motor 4 is started to rotate, an FG pulse is outputted from a fitted FG 6 and is counted by an FG counter 18, and its count becomes a prescribed value, a low level voltage corresponding to a count value of a target period is outputted from a period of an FG pulse immediately before the FG pulse at the prescribed count value.
