It has a base horizontal speed for stylus, then when there is a tracking error detected, it does a correction. So far, things are normal, but then, (according to literature) it *corrects* the horizontal speed to match the record! So for most of the record (other than the first few "learning" tracks) it is nominally more or less tracking the groove center rather than being dragged across as in normal tonearms. Of course, even at the correction point, the arm is close to tangential anyway. This turntable also has the Biotracer type mechanism that gives an effective arm mass of zero in both x and y directions. I'd agree that a CD player would be a better choice of purchase though,my Sony PSX-800 went for about $550-600 mail order from a discount place (plus another $125 for the cartridge) Mike Kersenbrock Tektronix Microcomputer Development Products Aloha, Oregon
