Always wondered how sound comes off tape. Back before tape was even invented it’s incredible how someone even thought of that

I've been searching for a good explanation how tape works. I did not expect to find the only good video about it in a video with so little views. Thanks for your video.

Thanks for this helpful explanation, I was wondering how just a strip of plastic tape could store data, I would have never imagined it was magnetized tape with a receiver head to read the tape. Its actually a genius idea. Now I know!

ME TOO. THEY WERE SO AWESOME THERE'S NO WORDS. HONESTLY THE ANALOG SOUND QUALITY TO ME JUST IS HEAVEN. THERE'S NO WORDS. AS A MODERN MUSIC PRODUCER I STILL PREFER IT TO THIS DAY. I DO SO MUCH ANALOG SOUND. BUT CASSETTES WERE MY PERSONAL ALL TIME SOUND CAPTURE DESIGN EVER THOUGHT OF OR USED.

Brief, clear, informative. Great video.

What always strikes me as magical is that sure it can capture sound through magnets and tiny electrical charges...but that it reproduces the nuances of speech, individual voices, the exact sound. If it just reproduced a kind of electrical robotic representation that would be incredible but that it can reproduce such exactness is amazing. To me anyway.

You have explained in very simplistic and powerful way, thank you. Keep on doing videos man, you deserve more recognition.

I've been remastering and recording music unto Cassettes since I was a kid, and till this day I still do. I just purchased brand new blank Maxell UR 90 tapes at Fred Meyer to continue transferring all of my favorite music unto an Audio Compact Cassette Tapes. I've been messing around with Audio Compact Cassette Tapes all my life, to show people that it's possible to make them sound Louder Sharper and Cleaner than CD's and especially MP3's! Anytime I would shop around for a new Professional Studio Quality Audio Compact Cassette Tape Deck, first thing that I would do is check out what Playback/Record Heads it's equipped with, and always make sure that it's also equipped with an actual AC Bias Erase Head instead of a permanent erase magnet (which are usually blue, but could be any other color). Avoid stereos that use such a permanent erase magnets since those (blue) erase magnets tend to add awful thunder-like noise to the tape, as it erases it. You can use those stereos for Playback-only, but never, ever record on such stereos. To record, I recommend using a 3-Head Professional Studio Quality Tape Deck if you want CD Quality Audio Recording on your tape. Like I mentioned before, all of my Compact Cassette Tapes sound Louder Sharper and Cleaner than CD's and especially MP3's! Every tape deck uses a different type of Playback/Record Heads. I always go for the Parmalloy AC Bias Head. Deck with a high quality Heads and an AC Bias Erase Head will guarantee that your tapes will sound Louder Sharper and Cleaner than CD's! But I also increase the Recording Volume (Not too much where the sound quality might get distorted), and increase the Bias levels, and I never use Noise Reduction to my recordings, since it's not the tape that hisses, but the stereo system itself hisses. Don't believe me? With no tape loaded in the deck, press play, and increase the volume. Hear that hiss? It's the same hiss that you hear in the background as the tape plays. Sometimes, especially on cheaper Stereos, that hiss that the stereo produces, gets recorded on the tape, that's why I only record on Professional Studio Quality Tape Decks that don't hiss like a snake. People get amazed how I accomplished to make Compact Cassette Tapes sound Louder Sharper and Cleaner than CD's and especially MP3's! Just gotta know how the tape recorders work, then you'll be able to get them to sound Good! And remember, it's not the Tape that hisses, the stereo system itself produces that hiss!

OH, Okay. I knew how Vinyl Records worked (Vibrations etching themselves onto a physical medium), but I had no idea that Magnets were what made Tape Media works. Thanks for clearing that up!

You sound like great scientists 🌹❤👌🏻👍🏻

The LED illumination is clever and accurate. The description of how the recording surface of tape works, however, is not. Magnetic pigment, whether ferric oxide, cobalt-enhanced ferric oxide, chromium dioxide, barium ferrite, or metal particle, is billions of magnetic crystals that are ALREADY polar magnets with a positive charge on one end of each crystal and a negative charge on the other. Recording does not "permanently" magnetize them. If it did, tape could not be erased or recorded over again. The recording process, which is described correctly through the record head, merely makes patterns of positive/negative magnetic "prints" on the tape that correspond to the electrical changes coming to the record head. The magnetic crystals in the pigment are fixed in place in a binder glued to the base film. The crystals can't physically move, but they can switch their magnetic poles under the influence of the magnetic flux coming from the record head. When most crystals have their positive poles lined up the same way, the output to the playback head is positive. When most poles are lined up with negative poles first, the output is negative. When poles are completely random, there is no output (except noise from broken or misshapen crystals.) Tape is erased when the erase head puts out a "loud" signal that changes so quickly that the crystals are scrambled randomly trying to keep up with the changes.

I liked this video, very helpful!

Nice job here. A thought occurs, about this subject: I grew up with audio cassettes in the 70's and 80's, and never understood why manufacturers of tape decks (whether it was a little shoebox tape recorder or a massive, pricey machine) would always place the Record button right next to the Play button. It's almost as if they wanted us to screw up and accidentally start erasing what we already recorded. Just a little mystery of life that I found annoying. 😄

Because when you record something onto tape you have to press the play & record button at the exact same time to make it record. If you just hit record it won’t work. They put them right next to each other so you can press them both with one finger to record. It’s much easier than trying to press them both with 2 different finger at the exact right time

@eduardo_corrochio

Жыл бұрын

@@crystal6368 Right, I get what you mean there, when it comes to those specific recorders that had the record/play "one touch record" function. The purpose was to make it more convenient. However, some machines were designed so that you can record just pressing the _Record_ button, and it's right next to the _Play_ button. Frankly, the manufacturers of stereos--- be they American or German or Japanese or Korean or Chinese-- all they had to do was put _Record_ on one end of the deck and _Play_ at the other end. The buttons have no business being next to each other. And it's not like the majority of consumers are spastic and have trouble with their finger dexterity. :D

I find it interesting that contrary to my uninformed expectations, the "magnetic signal" recorded onto the tape doesn't just dissipate, because as far as I know, a ferromagnet like the one you showed us in the video slowly loses its magnetism, doesn't it? And on an entirely different note, all that high-school dreariness about electromagnetic induction would have been made slightly more interesting if some of the applications were also mentioned.

@GlevoTec

2 жыл бұрын

Yes, that's true. The magnetism slowly weakens over time. This causes the tape to sound wrong after long time storage. Same reason why you shouldn't store it near magnets, because the magnetic field will affect the tape's magnetism, making it sound wrong, noisy or even erase parts

It does lose its magnetic charge over time. Like when an old music cassette where the notes sound false. But the material is made to hold to the charge for a very long time, but not forever indeed.

While recording, The tape is magnetized in the same patern as it receives signals from the drum that is placed nearby. Now while playing, it reverses the action. The magnetic field on the tape produce same pattern of current as it had received earlier, Which is again amplified, and music starts playing in the speakers.

Sadly my electronic technology course overly concentrated on digital electronic communications & microprocessors. The really interesting & enjoyable technology is analogue audio. The late '60's, '70's & '80's were arguably the best years for analogue audio. Digital technology is mostly black boxes & software.
