The memory model for the two hour CVR is physically constructed as illustrated in
Figure 12. There are a total of 15 X 32 Mb memory devices allocated to the four
partitions as shown. The 30 minute CVR contains a total of 7 X 32 Mb memory
devices allocated to just the first two partitions, for the HQV and HQC channels.
Due to the amount of sampling required for high quality channels, it takes almost as
many memory devices for 30 minutes of high quality recording as it does for 120
minutes of standard quality recording. For 30 minute recorders the total amount of
physical memory capacity is 24 megabytes. For 120 minute recorders the memory
capacity is 60 megabytes.
