Then, when the second tune is erased by editing based on the TOC information rewritten in the shock proof memory 5, the TOC information as shown in FIG. 4C is rewritten in the TOC area of the shock proof memory 5. Further, when editing is performed based on this TOC information and the second music and the third music are connected, the TOC information as shown in FIG. 4D is recorded in the TOC area of the shock proof memory 5.

However, since the editing after the recording was wrong, the button or the like which is the read operation means provided in the input device 16 is pressed, and the optical pickup 1 reads the TOC information from the disc 21 as an RF signal. Then, this RF signal is amplified by the RF amplifier 2, demodulated or subjected to predetermined signal processing by the signal processing circuit 3 to be restored as TOC information, and then sent to the memory controller 4, where the shock proof memory 5 displays it.

The case where the remaining area from address 0300 to FFFF is used as the voice storage area will be described.

For example, if the latest TOC information in the shock proof memory 5 is read by the system controller 12 and then the second song is erased, the system controller 12
The TOC information read out is changed to the corresponding TOC information, and the changed TOC information is rewritten in the TOC first storage area as the latest TOC information. After that, when the third song is erased based on the latest TOC information, the TOC information of the system controller 12 is changed to the corresponding TOC information and is stored in the TOC first storage area of the shock proof memory 5. Latest T
After the OC information is rewritten in the TOC second storage area, the changed TOC information is stored in the first storage area of the shock proof memory 5 as the latest TOC information.

If it is desired to cancel the erasure of the third piece of music, the selection means provided in the input device 16 selects the previous TOC area stored in the second TOC storage area, and the TOC information is stored.
