Good Day,

   Just two basic questions:

   - Are the track on a videodisc mastered as successive embedded circle or do 
     they form a long continous spiral?  The literrature is not specific about 
     this, or seem to contradict itself.

   - In the case of a circular arrangement, is the number of frame per
     track in CLV format an integer value (i.e 1 in the center and 3 
     outward?).  In the spiral case, it seem to me that you could put more
     than twice the amount of frame on a 12 inch disks....
   
   Please try to E-Mail.  If there's interest, I'll summarize to the net.

   Thank you!
   Daniel.
