Abstract
PURPOSE:To shorten the operating time of a track jump by moving a recording and reproducing head according to the information of the quantity of a movement from a moving direction and a current position for designating the position of a new head fed from a host device. CONSTITUTION:The host controller A feeds the information of the jumping direction and the number of jumping tracks of an optical head to a drive device B with a command. A controller 27 receiving the command detects that the optical head traverses a guide means and when the number of the guide means traversed by the optical head 12 reaches the number of the tracks jumped by the command, the track jumping is completed. Thereby, an address recognizing operation in the vicinity of the start of a SEEK operation is saved and the operating time for the track jump can be shortened.
