Not exactly, real QD disks were tested and approved for that track density. I think they are physically the same as DD disks, but were more expensive. I have some disks here that say "96/100 tpi certified, two sided/double density", made by BASF. They run fine in a 8250 and SFD1001, but so do many DD disks.
