| Q1: |
What kind of problems can occur when using 4x writing-speed DVD+R discs? |
| A1: |
The following errors may occur if these discs are used in some manufacturers' 2.4x writing-speed
DVD+R/+RW drives. Drives conforming to 4x writing-speed are excluded from this issue.
Typical errors are:
| • |
Recording cannot start. |
| • |
Data reading is not possible. |
| • |
In the event that a 4x speed DVD+R disc is recorded on a 4x DVD+R/+RW drive using packet
writing mode, and then additional data is recorded on to the same disc using a 2.4x DVD+R/+RW drive, there
could be the risk that recorded data cannot be retrieved. |

Q2: |
What is the source of these problems? |
| A2: |
It is the result of unsupported recording firmware in certain 2.4x writing-speed DVD+R/+RW
drives that do not conform to using 4x writing-speed DVD+R discs. |
