CD wallet inserts... cross-hatched design

[incredidome]

I have been using a 200-capacity CaseLogic CD wallet for DVD-R storage and since I have become more aware about my DVD care I couldnt help notice the cross-hatched, diamond design of the DVD inserts, like shown in this image (I used mspaint, but you get the idea):

Some questions (newb ones, but please help):

1) I would think that discs are supposed to avoid abrasive (rough, nonflat) surfaces like these. Does this surface scratch my DVD-R's (even if they're so small I cant see them)?

2) Why can't they just make the surface completely flat (like a DVD case)? Is this way somehow superior?

3) Are CaseLogic typically a consistent, dependable brand? Do they know what they're doing (how to treat DVD's)?

4) It is advertised as a "CD wallet," so does this mean its good for DVD's too? (I've heard scratches dont effect CD's as much because they have more read room, so I am thinking CaseLogic accepts that CD's will be scratched by the surface but with little harm and will still be able to read, but could severely harm a more fragile DVD, thus its advertised as a CD wallet)

Newb questions, yes, but I would really love some answers.. thankyou

Anyone please?

Wallets scratch discs easy and can warp media. It is true this has less effect on CD due to less dense write areas, but it's far more damaging to DVD.

Thanks for the response...

But what I am mostly wondering is the diamond, cross-hatched CD insert surface design itself harmful to the DVD's?

Or does CaseLogic know how to properly design an insert so they dont scratch the DVD?

(Why can't they just make the insert surface COMPLETELY FLAT?)

Aren't CD wallets technically OK as long as the user is careful (i.e. not letting CD's rub across jagged zipper, or accidentally carrying upside down and all CD's fall out)??

Basically, everything you asked has a negative answer. You risk damage every time a wallet is used, regardless of what it is made of, or how it is made. A wallet is a wallet, they are all the same, in the ways that it matters.

Sure, I use them myself, for certain things. But I accept the risks. When I use a wallet, it's for something I may not access more than once a year.

I use them for discs I carry around that I have other copies of (like my PC fixit discs). HAVE A BACKUP! Technically, if the materials are softer than polycarbonate, they shouldn't scratch. BUT it's not the materials - it's the dust, and the fact that you have that dust right against the disc surface (unlike in a DVD or jewel case) and are rubbing it against the surface (again, unlike other cases).
