Normally a standard laservision formatted videodisc will hold 54,000 frames 
or 30 minutes of video at 30 fps (non-drop).  I think you may be confused 
about just what it is that you store on a video disc, though.  They are an 
analog media like video tape rather than a digital media like CD-ROM.  In 
order to store a computer generated graphic, the graphic must first be 
rendered and then transfered to some intermediate analog media (usually 1" 
type C video tape).  The tape would then be send to a facility that could 
create the disc for you.  Going direct to disc is possible if the computer 
that will generate the image can be transported to a disc cutting facility. 
There are a variety of non-standard video disc formats for which you can buy 
portable laser disc recorders (such as the Sony LDR-5000) but they cannot 
play back standard discs and the discs they record cannot be played back on 
standard players.
