ABSTRACT:
The disclosed head moving device linearly and intermittently moves a head, such as a recording or reproducing head, a predetermined unit amount. A moving mechanism linearly moves the head in response to the rotation of an output shaft of a motor. A rotation component operatively connected to the output shaft of the motor rotates in response to the rotation of the output shaft so that one revolution of the rotation component corresponds to the predetermined unit amount of movement of the head, and an arresting element arrests the rotation component every revolution.
