| Playback error | The playback data contains an error | — |
| ||
|
| that cannot be corrected, and re- |
|
| ||
|
| reading (retry) of the relevant section |
|
| ||
|
| was repeated. As a result, the FIFO |
|
| ||
|
| memory became empty, and the output |
|
| ||
|
| data is interrupted. |
|
|
| |
|
| *During this retry operation, the data |
|
| ||
|
|
| remaining in the FIFO memory is |
|
| |
|
|
| output until the correct data is read. |
|
| |
|
|
| If the correct data is read before the |
|
| |
|
|
| FIFO memory is emptied, playback |
|
| |
|
|
| continues normally and the mark is |
|
| |
|
