groove. Each field has a unique DAXI code that is sequential to the<br />
previous one. If you take a disc out of a jacket and look at the pattern<br />
, you will see areas that are identical. This is the NTSC vertical<br />
interval. If you have a very bad disc, try making a clock out of it.<br />
very cool looking. Rather large though.<br />
Next was the delamination of the LD's. This was a major problem for<br />
LD's and there were many recalls of titles. LD's were produces as two<br />
separate discs and then laminated together. A process that was never<br />
fully perfected until later. As you might recall the number of LD's was<br />
greatly reduced after the demise of <strong>CED</strong>.<br />
Well sorry for all the ramblings, but you seem like a group that might<br />
appreciate the info and it is fun recalling a really exciting,<br />
stimulating and rewarding time in my engineering career.<br />
Regards to all,<br />

There is nothing wrong with MPEG per se. It can meet<br />
broadcast specifications IF you want it too.<br />
MPEG-I is pretty attrocious at it's best.<br />
MPEG-2 can be good if you let it. It's the problem of varying<br />
levels of compression that are chosen that can make it pretty<br />
bad.<br />
However since the DVD is being pushed to the consumer market -<br />
and the LD is held as an 'elitist' format - I wouldn't be<br />
surprised if the 'bean counter' mentality holds and higher<br />
compression is used to get more time per disk.<br />
There have been 6 video disk formats so far in this century.
