Has anyone had mis-tracking problems with their cd player? If so, what were the surrounding details? On my player, a TEAC PD-11, I've come across two discs which mistracked. The first had a 64th inch deep 32nd inch wide "gouge" which spiralled into the last "cut" on the disc. The player hangs up in the "groove" much like a record. The second disc could best be described as having a frosted splotch about 1/8 inch diameter. When mistracking first occurs, it plays each track two or three times before going on; finally hanging up indefinitely. An early SONY unit got hung up earlier from smaller scratches on said second disc, but a later SONY model performed as the TEAC on the same disc. A MAGNAVOX apparently played right through the same blemish! Early theory is that the "faster" the servo-mechanism, the more likely the unit will mistrack. The MAGNAVOX was very slow in aligning to a given track. Anyone else had any similar experiences, and or solutions? Polishing out the defects has not been tried yet, nor has anyone attempted to slow down the response time of the faster players. GEORGE

I've had the frosted splotch one one disk, and a second disk that wouldn't load at all. A friend had a splotch on a disk. Both disks mistracked by locking into a repeat mode, and even backing up in time when advanced past the spot. These three problems were all on London disks. We returned the disks, rather than try to polish/correct the problem. -- Pete Stumpf ..!ihnp4!homxa!stumpf US MAIL AT&T-Labs Room WB 1L-331/Crawford Corners Road/Holmdel,NJ 07733 Phone 201-870-7368

Yes, I have one disc that gives my CD player problems. It is a recording of the Thompson Twins, 'Into the Gap'. At a point about 3 minutes into the fourth cut, there is a 1 second period that my player almost mutes. (It sounds like the kind of mistracking one would get on an LP if the tracking force was too light). The curious part of this is that there is no visible damage to the CD, and my dad, who has the identical player (Revox B225), can play the disk without incident. I am wondering whether I should send my player back to Revox to have the error correction facilities checked out.... Ben Broder ..vax135!petsd!moncol!ben ..princeton!moncol!ben
