    Abstract: THERE IS DISCLOSED A DISK RECORDING/REPRODUCING APPARATUS IN WHICH A RECORDING AREA FOR ADDITION DATA IS ENSURED IN A REPRODUCTION OR PLAYBACK ONLY AREA WHERE RECORDING DATA OF THE SAME DATA STRUCTURE AS THAT OF A RECORDING/REPRODUCING AREA ARE RECORDED, THUS MAKING IT POSSIBLE TO REPRODUCE THE ADDITION DATA ALONG WITH THE RECORDING DATA.COMPRESSED DATA OBTAINED BY IMPLEMENTING, BY USING AN ATRAC ENCORDER 13, DATA COMPRESSION TO SUCCESSIVELY INPUTTED DIGITAL DATA IS DIVIDED INTO CLUSTERS, AND CLUSTER CONNECTION SECTORS LONGER THAN AN INTERLEAVING LENGTH ARE PROVIDED AT THE CONNECTION PORTIONS OF RESPECTIVE CLUSTERS TO IMPLEMENT INTERLEAVING PROCESSING TO RECORDING DATA TO RECORD THEM INTO A RECORDING/REPRODUCING AREA OF A MAGNETO-OPTICAL DISK 2, AND TO REPRODUCE THEM BY USING AN OPTICAL HEAD 3. FROM A REPRODUCTION OR PLAYBACK ONLY OF THE MAGNETO-OPTICAL DISK 2, ADDITION DATA ARE REPRODUCED FROM SECTORS CORRESPONDING TO THE CLUSTER CONNECTION SECTORS. (FIG. 1)

    Abstract: DURING RECORDING INPUTTED DATA ARE SEQUENTIALLY WRITTEN INTO A MEMORY (14) AT ONE TRANSFER RATE AND ARE READ OUT AT A SECOND, HIGHER TRANSFER RATE FOR RECORDING ON A RECORD MEDIUM (2). THE READING OF THE MEMORY (14) IS SUCH THAT DATA IN A PRESENT FIRST AMOUNT ARE SUCCESSIVELY READ FROM THE MEMORY (14) TO ALWAYS ENSURE A WRITE SPACE IN THE MEMORY (14) WHICH HAS A CAPACITY WHICH IS HIGHER THAN A PREDETERMINED SECOND AMOUNT WHEN THE AMOUNT OF THE INPUTTED DATA STORED IN THE MEMORY (14) EXCEEDS THE FIRST AMOUNT. DURING PLAYBACK, THE RECORDED DATA ARE REPRODUCED AT A SECOND TRANSFER RATE, WHICH IS HIGHER THAN A FIRST TRANSFER RATE REQUIRED FOR OUTPUTTING THE REPRODUCED DATA, AND ARE WRITTEN IN A MEMORY (22). THE THUS WRITTEN DATA ARE SUCCESSIVELY READ OUT OF THE MEMORY (22) AS REPRODUCED OUTPUT DATA AT THE FIRST TRANSFER RATE. THE WRITTING OF THE REPRODUCED DATA TO THE MEMORY (22) IS CONTROLLED SO THAT A SECOND AMOUNT OF THE REPRODUCED DATA IS WRITTEN INTO THE MEMORY (22) AND AN AMOUNT OF REPRODUCED DATA, NOT LESS THAN A FIRST AMOUNT, IS ALWAYS STORED IN THE MEMORY (22) WHEN THE AMOUNT OF THE REPRODUCED DATA STORED IN THE MEMORY (22) BECOMES NOT HIGHER THAN THE FIRST GIVEN AMOUNT.(FIG.1)

    Abstract: A DISC-SHAPED RECORDING MEDIUM (1) HAS A DIAMETER OF NOT MORE THAN 80 MM AND A RECORDING TRACK PITCH OF APPROXIMATELY 1.6 UM. IN EXCESS OF 130 MBYTES OF INFORMATION IS RECORDED IN A DATA COMPRESED STATE ON THE MEDIUM (1), WHICH IS ROTATIONALLY DRIVEN AT A CONSTANT LINEAR VELOCITY FOR RECORDING AND OPTICALLY REPRODUCING THE INFORMATION. A RECORDING/REPRODUCING APPARATUS FOR THE MEDIUM (1) INCLUDES A BUFFER MEMORY (23) BETWEEN A DATA COMPRESSING CIRCUIT (23) FOR COMPRESSING INPUT DIGITAL DATA AND A RECORDING ENCODING CIRCUIT (26,27) FOR PROCESSING THE COMPRESSED DATA BY MODULATION SUITABLE FOR RECORDING, AND A BUFFER MEMORY (25) BETWEEN A PLAYBACK DECODING CIRCUIT (33, 26) AND A DATA EXPANSION CIRCUIT (23) FOR EXPANDING THE COMPRESSED DATA TO THE ORIGINAL STATE. THE CAPACITY OF THE BUFFER MEMORIES (25) IS SELECTED SUCH THAT RECORDING AND REPRODUCTION MAY CONTINUE SATISFACTORILY EVEN IF THERE IS A TRACK JUMP DURING RECORDING OR REPRODUCTION. (FIG.6)

    Abstract: A DISC-SHAPED RECORDING MEDIUM (32) HAS COMPRESSED AUDIO DATA RECORDING THEREIN. THE INNER DIAMETER (DI) OF A DATA RECORDING REGION (RA) IS SET TO A VALUE IN A RANGE OF 28 TO 50 MM. THE OUTER DIAMETER (DO) OF THE DATA RECORDING REGION IS SET TO A VALUE CORRESPONDING TO THE INNER DIAMETER SUCH THAT, FOR THE LOWER LIMIT VALUE OF 28 MM FOR THE INNER DIAMETER THE OUTER DIAMETER IS IN THE RANGE OF 58 TO 62 MM, WHEREAS FOR THE UPPER LIMIT VALUE OF 50 MM FOR THE INNER DIAMETER THE OUTER DIAMETER IS IN THE RANGE OF 71 TO 73 MM.
