Packet Layout for DDCD

The layout of a Packet on DDCD media is shown in Figure 5. Each packet starts with Link block followed by three Run-in blocks. The User data blocks are placed directly after the Run-in blocks. Finally, three Run-out blocks are located following the User data blocks. In the case of Fixed packet writing, the size of each Packet in a Track is constant in length.
