Abstract
Abstract A disc recording and reproducing device includes a recording start switch for starting recording on a disc in which a table-of-contents area is provided in addition to a recording area in which main information is recorded, an optical pick-up and a magnetic head for performing intermittent recording on the disc, a recording stop switch for stopping recording on the disc, a music head designation key and a music interval detection circiut for generating a pause signal indicating a pause in the main information during the recording on the disc, and a circuit including a system controller for detecting the pause signal and writing a stop address of main information recorded immediately before arrival of the pause signal and a start address of next main information to be recorded in the table-of-contents area during waiting time of the intermittent recording. A trouble occurring due to stoppage of supply of an electric power during continuous recording of plural music pieces on the disc in real time can be minimized.
