I've seen many, many posts on various forums and websites about how rare "quad-density" disks are. This name is a bit mis-leading, as they are actually Double-Sided, Double-Density, 96TPI, as opposed to the Double-Sided, Double-Density, 48TPI disks that most of us use with our vintage computers.
ANYWAY... I posted here a while ago about a company called Athana that still manufactures new 5.25" disks (and even 8" disks!). As it turns out, they even manufacture these supposedly rare DSDD 96TPI (or "quad density") disks! I have a Commodore SFD-1001 drive on its way to me, which is designed to be used with these disks, so I recently placed an order for a couple boxes of these disks, as well as some boxes of the 48TPI disks to replace aging ones I already own. Two days later, the disks arrived at my door! Granted, I live close to where the company is located, in the Los Angeles area, so it may take a day or two longer for others to receive their orders.
I just thought that owners of SFD-1001's or other drives that use these so-called "quad-density" disks would like to know that they're not so rare after all, and that there's still a company that's manufacturing them. For more info on just what varieties of disks they have, check out this page:

For both 48TPI and 96TPI varieties of 5.25" disks, they charge $7.95 per box of 10 when you order 2-4 boxes. They give discounts for orders of 5 or more boxes. Their toll-free phone number is on the website, which is the best way to get more info on pricing.
