PURPOSE:To set recording speed of a signal to high speed by reproducing the signal, storing it at a buffer and checking errors immediately after the signal for one track is recorded at a recording body and recording the signal for one next track when the errors are not found. CONSTITUTION:A signal formed by an original reading part 8 is stored at a picture memory 9, encoded by an encoding circuit 10, a signal of the first track is stored to the first buffer 4 for recording based upon a command of a control circuit 13 and through a change-voer switch 7 a signal of the second track is stored to the second buffer 5 for recording. A signal stored at the buffer 4 is stored through a change-over switch 6 and a code adding circuit 3 to an optical disk 1. The recorded signal is reproduced by an optical head 2, recorded to a reproduction buffer 11, checked by an error detecting circuit 12 and when errors are not found, the signal of the second track stored at the buffer 5 is recorded. |
