[QUOTE=euforia;2025723]i believe the X’s are in the dye layer… since they won’t show up unless you view it from a certain angle with some light reflection. I didn’t store in sleeves, only in their original cakeboxes, since its more of a long term backup kind of thing.
Hm… My perverted burner…[/QUOTE]
In my experience marks like that are almost always down to something being in contact with the disk when its burned, (leave a disk out to get covered in a SMALL amount of dust and burn it and you will see what i mean) tiny marks are indeed hard to spot until you angle the disk in light.
I had a similar issue with a couple of disks a year or so ago, except instead of a “X” pattern i ended up more with “#” marks all over the burned area, turns out after a heck of a lot of investigating it was down to a few plastic wallets i had stored the disks in. The textured plastic had either scratched or left dust/dirt makes on the disk which were not noticed prior to burning and the funny marks were the result. I have also heard of similar issues occuring to people that store NON-burned disks in those plastic wallets with a cloth divider in them.
However my issue was not anywhere near as bad as yours, i would have perhaps a dozen at the very most marks, your disks seem practically covered, so i spose it could also be the dye on the disk itself breaking down… was the media concerned cheapo rubbish, or known to be decent?
Finally id say alter the method of storage you are using, disk tubs are normally fine, but if you are regularly taking several disks out and putting them back its not unusual for non-used disks to get covered in dust or scratched.
