This is really more of a hardware question, but I figured I'd pose it here and if I'm way off base an admin will just up and move it. I have a series of questions about how DVD players spin and read discs: 1) Does the player begin reading at the outer, or inner edge of the disc? 2) Does the disc spin at a constant rate, or a variable rate? 3) Similarly, does a single frame of information on the outer edge use the same amount of memory/space as the same frame would on the inner edge? All of the above questions arose out a discussion of Laserdiscs and CAV vs. CLV. While we're at it, if somebody could confirm my LD understanding that would be great. As I remember it, LD's spun the disc at a constant speed when the disc was CAV (constant angular velocity) and changed the spin rate for CLV (Constant Linear Velocity). CLV was a much more efficient storage system, though, as a single frame took up the same amount of space regardless of it's location on the disc. CLV disc could not be played in slowmotion, or step motion though, as I remember, although there are probably players that can do this by now. I hope somebody can answer my DVD questions and confirm or correct my LD assumptions. Thanks in advance.
