Videonauhojen

Videonauhojen, often referred to as video tapes, are a magnetic storage medium used to record and play back video and audio signals. These tapes consist of a plastic ribbon coated with a magnetic material, housed within a protective cassette. The technology became widely adopted in the late 20th century, revolutionizing home entertainment and professional video production.

The most common formats for videonauhojen included VHS (Video Home System) and Betamax. VHS, developed by JVC, eventually became the dominant format due to its longer recording time and lower cost, despite Betamax offering superior image quality. Other formats like Video 2000, U-matic, and Betacam also existed, catering to different market segments and professional applications.

Recording onto videonauhojen involves a VCR (Videocassette Recorder) or a camcorder. The VCR reads the magnetic patterns on the tape, converting them back into visual and audible information for playback on a television. Conversely, it writes new magnetic patterns during recording. The magnetic particles on the tape degrade over time and with repeated use, leading to a loss of signal quality. This inherent limitation contributed to the eventual obsolescence of videonauhojen with the advent of digital storage and optical media like DVDs and Blu-rays. Despite their decline, many historical and personal recordings remain on videonauhojen, prompting efforts for digitization and preservation.
