Audio vs Video vs Data Tapes Explained (How We Store So Much Information Using Electromagnets)

We've been using tape to store information whether it be audio, video or data for almost a century, and yet there is some interesting engineering that went into developing this technology over the years. In today's video, we look at a technology that is (mostly) of yesteryear and explore how we actually stored information on what is essentially rust glued onto plastic.
In the video, I focus on the difference between audio, video and data tapes, and how we were able to store 1 hour of video in the same space as what previously held and hour of audio, and how we can store tens of terabytes today in the space of a single VHS tape using similar technology.
The tape era is really quite out of my knowledge realm. The comparison between audio, VHS, MiniDV and Video8 came up when I was trying to digitize all of these formats for a digital family album, which led to the realization that there must be a fundamental difference between how they work given what I know about the bitrates required in the modern world for digital audio and video.

For more on tape based audio and video, check out the channels of ‪@TechnologyConnections‬ and ‪@Techmoan‬, they've made more in-depth video about these topics.
I found out after recording this that Technology connections made a similar video on video tapes a few years ago, give it a watch too: • The Impossible Feat in...

Thank you for the video. I would be interested in understanding how audio ADAT’s work. Also with red book audio CDs how multisession recording was achieved with track at once compared to disk at once recording.

ADAT seems like a question for Techmoan :)
As for multisession, subsequent session just have their own lead in and since there isn't a final lead out, the drive will look for the most recent one from my understanding.
