LT-1

LT1 was one of several odd-sized floppy formats that never caught on. It was 2 inches in size, similar to the Video Floppy but not compatible with it. It was released in the late 1980s for the Zenith Minisport laptop. Disks were double-sided/double-density, with 80 tracks per side and 720 KB capacity.
