Make the problem disks more tacky by brushing them with a damp rag then dry and immediately insert in the PTR1. I find that the problem is often just a registration issue. If it can grab the disk and get a good fix on the track structure the issue is often resolved.

Michael - Have placed an order for one tub of 50, the price at £7.28 I thought was ok, but the postage of £4.80 is rather a lot. I don't actually want to record on to them using the PTR1, but to burn to them using my PC, and play them back in the PTR1; this is where I've been experiencing the problem, like I said earlier, all disks play in other players, but some of them won't play in the PTR1, I get that dreaded message "invalid or damaged disk." - Andy ----- Original Message ----- From: "Michael Lang" <michael.lang@xxxxxxxxxxx> To: "Andy Collins" <ptr1-users@xxxxxxxxxxxxx> Sent: Saturday, April 28, 2007 6:29 PM Subject: Re: Which blank media for the PTR1 is recommended? | Andy, you wrote: | | > Michael - I'm in the UK.
