Cassette tape (format)

From Wikipedia, the free encyclopedia
(Redirected fromAudiocassette)
A SonyCompact Cassette.

Cassette tape, also known as simplycassette, refers to a small plastic unit containing a length ofmagnetic tape on two reels. The design was created to replicate the way areel-to-reel machine works with tape moving from one reel to another while being read by atape head. The design was first made for audio formats but then expanded into video and data storage.

As of 2024[update], although the cassette format is no longer used for video or data storage, it is still used as an audio format with many consumers still purchasing new album releases on cassette.[1]

Terminology

[edit]

The term cassette mainly refers to a unit that has two reels inside. While some of the first cassette formats also used the term "cartridge", in modern usage the term "cartridge" and "tape cartridge" usually refers to a plastic unit that only has one reel of tape and companies that make and sell both type of formats likeFujifilm orMaxell also make the same distinction.[2]

History

[edit]

Magnetic tape became a popular method to record and play back audio and video recordings withreel-to-reel machines being used for audio withaudiotape andvideotape becoming an easier way for TV stations to broadcast TV shows and record news programs.[3] The medium served as an easier way to preserve and store media as well as play it back that didn't come with the hassle of something like vinyl or setting up film projectors for home use or having to deal with satellite interruptions for broadcasts of video for TV stations.

Over time, magnetic tape became the main way that media was stored and accessed. As the format became more ubiquitous, the hassle and difficulty of managing reels of tape for both consumers and professionals became evident even when the reels came in smaller, portable sizes. Many companies tried to come up with a method of storing the tape in an easier format. This led to the creation of magnetic tape stored in cases known as "tape cartridges". Many of these cartridges would house the tape inside on a single reel with the tape either being exposed on one side so the tape head could read it like8-track cartridge or have a mechanical system that would pull out the tape to read it likeVideo Cassette Recording byPhilips.

RCA then introduced theRCA tape cartridge in 1958, an audio format which worked similarly to a traditional reel-to-reel machine but instead of providing the tape in one big reel, the tape came enclosed in a case that had two reels built into it that would run the tape from either side.[4] This would remove the hassle of setting up a reel-to-reel deck and winding up the tape to the other side of a machine in order to play it. It also allowed a more reliable way to play back the tape instead of the single reel system other cartridges used. It wouldn't be until 1963 with the introduction ofCompact Cassette that this dual reel system would become the standard and also introduce the termcassette for these cases. The term "cassette" came from French which meant "little case".[5] This would then be followed by video formats withU-matic becoming a standard for video broadcast on the professional, TV segment andVHS for consumer, home video.
