A:Answer These are not tapes-they are mini-DVD's to fit in a DVD Camcorder. All PC's and DVD-ROM players also accept these as there is a built in indentation for this size disk as well as the full size CD or DVD. Too many Manufacturers to name but a few are Sony, Panasonic, Hitachi, Samsung, GE, and Phillips. Most will record DVD +R and -R disks, as well as DVD-RW disks. They are all different formats, but the Manufacturer usually makes it compatible with a variety of blank DVD's.
