8 mm videotape format which provides better quality than VHS. An improved version of the 8 mm tape format capable of recording better picture resolution (definition). A higher-density tape is required which provides a wider luminance bandwidth, resulting in sharper picture quality (over 400 horizontal lines vs. 240 for standard 8 mm) and improved signal-to-noise ratio. Camcorders using this format are very small, light, and provide a picture quality similar to S-VHS.
