Videotallennuskasetteja, commonly known as VHS tapes, are magnetic tape-based recording media used for storing analog video and audio signals. Developed in the 1970s by JVC (Japan Victor Company), VHS became widely popular in the 1980s and 1990s as a standard for home video recording and playback.

A standard VHS cassette consists of a plastic shell that encloses a spool of magnetic tape. The tape is coated with ferromagnetic material, allowing it to record electromagnetic signals. The cassette includes a tape transport mechanism and heads that read and write data onto the tape when inserted into a compatible VCR (Video Cassette Recorder). The standard size of a VHS tape is approximately 10.5 cm in length and 1.6 cm in width.

VHS tapes are capable of recording several hours of video, with typical durations from one to six hours, depending on tape length and recording quality. The tapes are used for various purposes, including home video recording, rental movies, educational content, and personal archiving. The format's widespread adoption made it a dominant medium for home entertainment before being largely replaced by digital formats such as DVD, Blu-ray, and streaming services.

Despite their obsolescence in the digital age, VHS tapes remain of interest for collectors, archivists, and enthusiasts who value their nostalgic and collectible appeal. Several companies continue to produce blank tapes and VHS-compatible equipment, maintaining a niche market. The technology's legacy includes influencing the development of digital recording media and contributing to the popularization of home video entertainment.
