Video Floppy , also known as VF disc and introduced under the "Mavipak" name, is an analog recording storage format for still video cameras. It consists of a 2-inch magnetic floppy disk used to store still frames of composite analog video.
A video floppy could store up to 25 frames either in the NTSC or PAL video standards, with each frame containing 2 fields of interlaced video. The video floppy also could store 50 frames of video, with each frame of video only containing one field of video information, recorded or played back in a "skip-field" fashion.
