Double Density CD - Page 5

- Recording methods:
The DDCD format is supposed to support: "DAO, SAO, TAO" formats. Our tests showed that only "TAO" writing mode, Packet Writing and Multi-Session are supported. In the case of Packet Writing we will have 2 modes: Variable Packet Writing and Fixed Packet Writing (no futher information is given about their main differences). There seems to be a limitation with MultiSession of the DDCD and CD format as the following table shows:

As it is obvious, you cannot backup CDs which contain multiple sessions in DDCD-R/RW media, and vice versa.

- Recording speeds

The DDCD format has mainly 2 different writing/re-writing speeds. The DDCD-R media can be written at 12x and the DDCD-RW media at 8x. In other words, you will need around 12 minutes to burn a full DDCD and around 15 minutes for a full DDCD-RW media. We hope that newer DDCD models will support higher recording speeds (16x) and, why not, a full 10x re-write mode.
