It consists of a 2-inch magnetic floppy disk used to store still frames of composite analog video.
The recording media in a video floppy is a flexible magnetic disk 47 mm (1.9 in) in diameter and 40 μm (0.0016 in) thick.
The Hi-Band format developed in 1988 shifts the luminance signal to between 7.7 and 9.7 MHz, improving the signal-to-noise ratio and resolution.
[3] The patent for the data variant of the Video Floppy was filed by Ken Kutaragi and assigned to Sony Corporation.
[6][7] A similarly sized disk was also used by the Zenith MinisPort laptop computer from 1989, digitally formatted for data storage.
[9] An enhanced version of the VF format called Hi-VF was introduced in the late 1980s, providing higher resolution per video still than its predecessor.
