Even this is impossible. The CD has only one track or "groove", just like an LP. It would be difficult for a servo system to track bits on the hi-density CD like the stepper system on the relatively low density magnetic platter. But of course, I'm off the subject. This has nothing to do with DSP... -- Todd Day | todd@appmag.com | appmag!todd@hub.ucsb.edu ^^^^^^^^^^ coming soon!
